Lens Hotspot Database

Unfortunately many lenses suffer from an infrared hotspot. We have compiled the world’s largest collection of lenses and their hotspot performance. The lists below are based on our own tests and what others have reported. Lenses with a * have had mixed reports or only have a hotspot in limited situations. Please note, even poor performers can generally be used. Most hotspots only occur at smaller apertures and some shooting angles.

Luckily we are now offering our new AR coated conversion filters that reduce hotspots, which improves the lenses on this list. It will take time for us to retest lenses, but you can generally expect that with the AR coating you will get several additional hotspot free apertures compared to what is on this list, making many of the poor performers usable.

Please note: This list has errors, or you may find lenses listed as “poor” that you use well. This is because this is a compilation from many different sources, and people have different judgements for what is acceptable. For example, a lens that has a moderate hotspot at f10, some people may use primarily at f6 and below and think it is a fantastic lens, while someone who uses the lens around f11 will think it is terrible, while yet another person may use it at f11 and think the hotspot even there is mild and can be worked around and still think its a good lens. Additionally, hotspots tend to be worse with deeper IR filters like the 850nm, than the color IR filters, like the 590. Ideally, every lens should specify the aperture range that causes hotspots, but until we get there, please take this list with a grain of salt, and if you find any errors, please let us know and we will fix it!

After you know what lens is good, order one on Amazon or Ebay, or have us convert your camera and calibrate it to that lens here.

  1. Now that Kolari Vision is offering AR coating for the sensors the Hoot Spot list will most likely need to be revised for people who get the AR coating.

  2. Konica 50mm f1.4 — terrible hot spot all the way down to f4
    Konica 57mm ƒ1.4 — no hot spot at all

    I test by using a tree in my alley and centering the lens int he open sky just above the bright trees. My camera is 720nm A7II. No AR coating.

    1. i bought and tried the Konica 57mm f1.4. correct, absolutely no hot spots any any setting. i also needed some wide angle so i also used my zeiss zf-ir 24mm f/2.8 lens and wow, there’s a big noticeable difference in contrast and sharpness without having to pixel peep. not bad, but i want something a little better so you’ll see one for sale on ebay soon.

  3. Samyang T-S 24mm f3.5 ED AS UMC on converted to full spectrum Canon 50D.
    Outstanding resolution, no hot spot on every aperture.
    Perfect for visible and IR spectrum.
    Tested on visible light, 690nm and 720nm.

  4. On a Canon 40D with 590nM conversion, I can confirm the Sigma 10-20mm f/4-5.6 EX HSM DC* hotspots that start to appear at f/13 and is visible at f/22. I’d say it’s mild from examples I’ve seen posted by others from other lenses.

  5. ZEISS 50mm f/2 Planar ZM T* : No problem at all
    Voigtlander 35mm f/2.5 Color Skopar Leica M mount : No problem at all
    Just to be more precise about the FUJI XF 27mm f/2.8, it’s usable at f/4 no hot spot visible,it begins to be very faint and wide at f/5.6, very bright small hot spot at f/16.
    All the tests were done on FUJI X-Pro1 camera.

    1. what about the Voigtlander 10.5 f/0.95? it’s not mentioned.

      1. The Voigtlander 10.5 f/0.95, on my Olympus e-m1 mark ii, has a medium intensity, huge hot spot right in the center.

  6. I just got testing a Sigma 35mm Art lens on my Kolarivision converted 60D and experience a hot spot at all apertures smaller than F2.8. The intensity increases as the aperture size decreases and is really intolerable at F6.7 or smaller. At apertures wider than F2.8 you really have to look for it.

  7. I’ve got the Fuji 16 F 1.4 – very bad at all apertures past F2.8 and not so good at 2.8 and lower. The only good thing to say about the otherwise wonderful lens is that the hot spot does not have a hard, harsh border, and is very wide – hiding the effect a bit.

  8. Samyang 24 3.5 ts-e don’t produce any flare.

  9. I would like to see the newer Fuji lenses tested. In my limited trials, I find the Fuji 35mm F2.0 to be an excellent performer, but the autofocus tends to hunt. The 16mm 1.4 is terrible. Autofocus doesn’t work at all. The 90mm is good from 2.0 to 5.6.

  10. So I have gone crazy with testing Standard/Normal old glass over the past three months. I shoot a pair of oak trees in front of my apartment building late in the afternoon. Testing season will be done soon 🙁

    Konica AR 57mm ƒ1.4 – fantastic lens both color and IR.
    Konica AR 50mm ƒ1.4 – well defined hot spot from ƒ4
    Konica AR 50mm ƒ1.7 – clean lens, great performer
    Konica AR 50mm ƒ1.8 – hot spot looks like smudges in the imager after ƒ11, also Ninja Star
    Mamiya Sekor 55mm ƒ1.8 SX – clean lens that has smudge Hot Spot after ƒ11
    Mamiya Sekor 55mm ƒ1.8 – clean great performer
    Olympus 50mm ƒ1.4 Zuiko – Ninja Star, and bad hot spot, really bad
    Olympus 50mm ƒ3.5 Macro Zuiko – lovely performer, sharp and no hot spot
    Canon FD 50 ƒ1.8 – clean great performer
    Canon FD 50mm ƒ1.4 – one of the worst from ƒ4 on
    Minolta MD 50mm ƒ2 – visible hot spot starting at ƒ8
    Minolta 50mm ƒ1.7 Rokkor – clean nice lens
    Minolta MD 50mm ƒ1.7 Rokkor-X – clean great performer
    Minolta MD 50mm ƒ1.4 Rokkor-PG – terrible hot spot one of the worst starting at ƒ5.6
    Minolta 50mm ƒ1.7 AF – clean but the lack of live preview of aperture is a no-go
    Yashica 50mm ƒ1.5 Yashinon DS-M – Bad, really bad, one of the worst
    Nikon 50mm ƒ2 Nikkor pre-AI – clean sharp and no hot spot
    Nikon 50mm ƒ1.4 Nikkor pre-AI – not terrible just unusable after ƒ8
    Nikon GN 45mm ƒ2.8 Nikkor – crazy sharp and no hot spot.
    Fuji 55mm ƒ1.8 Fujinon – Ninja Star, nice lens otherwise with slight smudging at tine apertures
    Pentax 50mm ƒ1.8 Takumar – No hot spot, but not as sharp or interesting as the Konica/Mamiya/Minolta lenses.

    So what can we learn from all of this.

    1. The Konica 57mm ƒ1.4 is the only ƒ1.4 that I have tested that has no hot spot at all. Combine that with it’s color performance and despite my best efforts to replace it, I still find it to be a winner.

    2. The color and bokeh of the ƒ1.4 lenses all made me happy with the exception of the Ninja Star issue on the Oly. If I was not shooting IR there is not a loser among the rest.

    3. I have not tested any m39, M, Pentax 50mm ƒ1.4, Leica R or Contax lenses.

    4. Simpler design seems to make for less hot spots. Though that is not always the case. The ƒ1.8-ƒ2 lenses seem at worst to have more of a smudging issue or than the cheap Minolta 50mm ƒ2.

    5. I own too many of these lenses and need to sell off most of them.

    1. Since these test I have tested a few more.

      Pentax 50/1.4 7 element — Only the 2nd 1.4 that I have ever tested that matches the Konica 57mm. I have also tested two different versions of the Konica and both have same great results.
      Pentax 35/2 Super-Takumar — big heavy lens that delivers fantastic results.
      Konica AR 135/3.2 Hexanon – my favorite 135 of all time. This lens is light weight, compact, crazy sharp, and clean hotspot results. Crazy short focus distance, if you love shooting flowers this is an amazing lens. I also bought it for $5 out of a bargain bin!
      Konica AR 35mm ƒ2.8 – older Hexanon version and excellent results.
      Konica 28/3.5 Hexanon – Great results some hint of smudging past f11.
      Konica 200/4 — great results. I love this lens.
      Konica 200/3.5 — great results
      Vivitar 200/3.5 m42 — Fantastic lens, great Hot Spot results.
      Vivitar 19mm/3.5 — Not the sharpest lens in my kit, but clean IR results
      Canon FL 85/1.8 – a lot to love about this lens other than weight — classic all metal construction, sharp and clean IR results.
      Canon FD 24/2.8 — some smudging at ƒ11
      Canon FD 35/2.8 – very clean results
      Nikkor 35/2 Pre-Ai, really nice lens with clean results.
      Nikkor 135/3.5 Pre-Ai, clean lens, just not as sharp as some of my other 135s
      Voigtlander 35mm ƒ2.5 MC LM — hot spots at ƒ8
      Minox Color-Minotar 35mm ƒ2.8 — this is m39 converted from the legendary Minox cameras and it gives great results. Downsides are 4 sided bokeh, and fidgety to use thanks to a tiny aperture ring.
      Topcor 58mm ƒ1.8 — I have two of these and was not impressed with either. Hotspots start at around ƒ11.
      YUS (Yashica) 28/2.8 C/Y — this is simply an amazing lens — my hands down favorite 28 for any purpose.
      YUS (Yashica) 135/2.8 C/Y — next to the Konica 135/3.2 this is the best 135 I have ever tested, sharp, contrasty, and no Hot Spot issues.
      Yashica 50/1.8 ML C/Y — stay below ƒ11 and watch how you shoot with it.

      There are other lenses I have tested and to be frank was not impressed. Hot spot issues were not terrible, just not what I was looking for in terms of other results:
      Hanimar 35/2.8, Pentacon 50/1.8, Fujinon 55/1.9, Miranda 50/1.9, Pentax 35/3.5, Pentax 200/4, Minolta 35/1.8 Rokkor-X, Minolta 135/2.8 Rokkor-X, Olympus 28/3.5, Nikkor 28mm ƒ3.5 Pre-Ai.

    2. I heard nothing but good things about the Minolta 57mm f/1.4 so i got one.
      it’s true. no hot spots and nice color, but it was not sharp at all. it’s cheaper and easier to just get a point and shoot modified camera if you want this kind of softness.

    3. I can add a lens to your list. The Minola MC ROKKOR-PF 58mm f1.4. I just compared it side by side to the Konica 57 f1.4. THEY ARE BOTH COMPARABLY SUPERB. If I had to choose, I’d go with the Minolta. But they’re both very close to perfect.

  11. fujifilm 23mm f2 has NO hotspots using R72 filters at any aperture

    new lens to add, been using same a LOT

    “angry photographer” on youtube channel , thats me

  12. You have it marked as good, but I’m getting large but faint hot spots from a Tamron 15-30 at mid-apertures on a converted D3300.

  13. What is the best way to test lenses for hot spots, so that I may add my lenses to this database? Do you have a recommended testing routine?

    1. Find a tree with full canopy of leaves. Set camera up on tripod and aim center at a sky just above the foliage. I have an Oak that has a nice V shaped area I aim at. You want a cloudless sky – make sure the sun is not in or near the image area. Shade it out if needed. I start at minimum f16-f22 and then work back in full stops while looking through the lens. If you are going to have an issue it will be obvious at smaller apertures. Most lenses with issues lose their spot at around f4-8. If you read my earlier note I have done way to much testing.

  14. Fuji 35/2 very good at all apertures. Database re: Fujifilm lenses agrees w/ my Pro & Con experience. Thanks for publishing the database

  15. Fuji 14/2.8 also very good at all apertures

  16. Tamron 15-30 hot spots fairly bad at smaller apertures.

  17. Your database shows that the OLYMPUS 12-50 has poor performance after f/9.
    The fact is : ALL 4/3 and micro 4/3 lens start to perform badly after f/8, from Diffraction Limit. No exception.

    I use 12-50 for over 1,000 images. None has hot spot.

    1. Note : Personal Opinion.

      Almost all MF lenses of film era have IR marking.
      Does that mean it have to be able to handle IR beautifully?

      If the MF is not tested on modified IR mirrorless camera, I believe that all MF lens will perform poorly because the IR ray __is designed__ to be focused at the different plane from visible light.

  18. Hello, I’d keen about what’s wrong with the Canon TS-E 24mm f3.5 L II, listed in bad performers: “Canon TS-E 24 mm f3.5 L II* (see comments for details)”. Cannot find anything in the comments here. Many thanks for your help!

  19. No dis-respect, but take this list with the proverbial grain of salt. Listed above as a “Poor performer” is the Nikkor 24mm F2.8. However, I get excellent results from my Nikkor 24mm, F2.8 on my converted D7000. Now I have the narrow filter, and shoot only in the deep 850 nm range.

    However, the Nikkor-NC Auto, 24mm F2.8 lens, all versions, is not a great lens. IR or everyday shooting. If you use that lens on any full frame camera, and compare shots side by side, you’ll see the difference in sharpness on any photograph.

    So I suspect the poor rep is based on the N or the NC version. This manual focus lens is still made new today. if any of you still want to dump one off cheap, just let me know. 🙂

    1. yes, the problem too is that i doubt people are testing every focal length on zooms and every aperture and every type of IR filter (590,665,720,850nm). so you’ll only get a general idea from this list but it’s the biggest list i’ve seen. hot spots are the most frustrating part of IR phtography.

  20. I find that Nikkor 17-55 has hot spots over f/5.6 or on times over 20 sec.
    The same with Nikkor 18-55 VR II but definitely less visible hot spots on this lens.

  21. i’d like to add to the list:
    olympus 12-100 f/4 (very bad hot spots)
    leica 8-18 f/2.8-4 (no hot spots)
    leica 12mm f/1.4 (no hot spots)

    1. I just ordered the Leica 8-18 for my fully converted Pen-F, thanks.

  22. Have you tested this lens?
    Canon EF 50mm f/1.8 STM Lens
    Thanks, John

    1. I went ahead and purchased this for $125 and it performs like a champ on my 850nm converted 5D Mark III. I sold my Sigma Art 50mm for a couple reasons and one of them was the terrible hot spot.

  23. Olympus OM 21mm f/3.5 Auto-W performs well from 660nm and longer wavelengths at f11 or lower without hotspots and very little chromatic fringing at corners at f8 or higher.

    1. Forgot to add “Zuiko” and MC (multi coated) to lens description.

  24. Voigtlander 15mm f/5.6 Heliar III, AWFUL HOTSPOTS at all apertures, increasing as they increase.

  25. Have anyone tested Sony GM 24-70 F2.8?

    1. I tried, Unfortunately poor perfomance

  26. The Canon 70-200/4 L non-IS model is in the Good Performer category. I had the IS model and I would put that in the Bad Performer list.

  27. Hello, Has anyone experience with the nikon 24-85mm VR, because does not saw on the list?! Thank you!

  28. has anyone tried the
    Zeiss 12mm f/2.8 Touit Distagon T*
    Sony 16-35 f/2.8 GM

    1. The 12mm Zeiss is my almost-full time lens on my Fuji X. I have 100+ images posted on Instagram with it. #zeiss

    2. The sony 16-35 G has hotspot starting at f/8

  29. Has anyone tried Tamron 10-24 VC (New model B023) or Sigma 17-50 OS??

    1. Forget sigma lenses, very bad for IR, tested several of them…

      1. Thank you for your input. According to this review, Sigma 18-35 is great for infrared. I wouldn’t discredit all Sigma lenses just yet.

        1. Well, I had one, so believe me it’s not good, this article it’s only about hotspot, probably is hotspot free, but it’s terrible otherwise…

      2. Old Sigma 12-24 has no issues – a wonderful overall lens and my go to lens for IR

    2. Have had great results with Sigma 17-50 830M IR Untested with 720 NM

  30. Has anyone tried the Voigtlander 10mm Hyper Wide (Sony E mount)?

  31. Has anyone tried the Neewer/Meike 35mm 1.7, 7Artisans 25mm 1.8, or Sigma 19mm 2.8?

    1. I just got a copy of the 7Artisans 25mm for my fuji x-e1. Happy to say that it is workinf flawlessly for me so far.

  32. On or Sony A7S the 24-240 lens produces hot spots most of the time. They can be corrected in Lightroom and Photshop, but it is annoying. Sony lenses generally has this problem.

  33. a few other aditional lensdata not in list, I take ir /uv photo’s since 2008 (modded Nikon D200): Good performers: Tokina ATX Macro 90mm f2.5 ; Tokina 17mm SL f3.5 ; Sigma EX 50mm DG; Sigma EX APo 100-300 f4 ; Sigma 180mm f3,5 APO Macro HSM; Sigma EX 15mm fisheye. Nikkor AIS 105mm f2.5 ; AIS 80-200 f4. E serie 35mm f2.5 also suberb in UV! AI Micro 55mm f3.5. Sigma EX 10-20 f3.5 does well. Samyang 14mm f2.8 UMC, IRIX 15mm f2.4 . Voiglander 40mm Ultron f2 (nikonversion) . BAd performers: Nikkor AIS 28mm f2.8 (with CRC) , Tokina ATX 12-24 f4 dx ,

  34. Anyone tried ultra wide angle performance of 7Artisans 12mm f2.8 and meike 12mm f2.8?

    1. The 7artisans 7.5mm f/2.8 fisheye works well enough in the infrared, with slight corner softness and slight color fringing in high contrast. I used f/5.6

    2. Looking for the same information myself. Any luck finding out more?

  35. Two more lenses for the list:

    Rokinon 24mm tilt-shift with full-frame Sony e-mount. No hotspots observed at all.
    Sony 70-300 G in full-frame Sony e-mount. Nasty hotspots at wide end, OK at 300 with widest aperture.

  36. what about the new Tamron 24-70 f/2.8 VC ?

    1. Hi,
      I also am trying to find out about this lens for infra red, have you had any luck with it?

    2. Hi again, So I have just tested out my Hoyar72 77mm filter on the Tamron 24-70 g2 lens, (I taped it onto the 82mm lens and blocked the edges as best as possible.)
      Pleased to report no visible HotSpots till f22, then of course it’s quite small by then.

      Here is a link to some test files….

      Just ordered a 82mm R72.

      Other data (camera exp, f, iso etc in the metadata of the files).

  37. Sony Distagon T* FE 35mm f/1.4 ZA Lens is pretty much garbage, you can use it wide open but it still has a hot spot at f/1.4

  38. Hello friends,

    How do they behave in Infrared Photography, the next lenses: the Canon 16-35 f/2.8 III and the Canon 24-70 f/2.8 II?

    Thanks for your help.


  39. Fujinon XF 10-24 f/4 – hot spot in the center. Rather bad…
    Fujinon XC 16-50 f3.5-5.6 – mild hot spot.

    Both tested on X Pro 1 converted to full spectrum.

  40. i get some hot pink in the center when doing faux color at f/11 with a Zeiss 50mm f/2.0 Makro-Planar.
    i don’t notice it when doing mono IR though. that is probably why it’s in the left/good column.

  41. Hi, I’m wondering if the samyang 10mm f2.8 ED AS NCS CS does the job in IR ?

  42. Does anyone know if any of Yashica’s lens (ML, MC, DSB, YUS, DX) have hotspots?

    1. YUS 28 and 135 are fantastic values and fantastic lenses with little or no Hot Spot issues

      50/1.8 ML has issues with small apertures, and the DSB 50/1.4 simply sucks at IR.

  43. IR 720nm filter converted Nikon D7000. I have tested 6 lenses, all of these are hotspot free up to f/8 (no reason to test smaller apertures on crop sensor, f/8 provides huge DoF, everything is in focus for most IR shots). The biggest difference between lenses is sharpness and color.
    – Sigma 50 Art, the best lens I have tried. No hotspots and very very sharp. Wickedly sharp.
    – Sigma 105 OS Macro, no hotspots and very sharp.
    – Sigma 18-35, no hotspots and very sharp. Corners are slightly soft at 18mm, but slightly zoomed in, the lens is sharp corner to corner.
    – Tamron 10-24 VC, very soft corners at wider angles, from 16-24mm corners are very good with very little softness. Center is very sharp throughout the zoom range. My favorite lens for IR.
    – Nikkor 18-55 VR1, no hotspots but very soft corners and widest setting, gets better when zoomed in, but overall sharpness is not as good as Tamron 10-24 or Sigma 18-35.
    – Nikkor 50 f/1,8 AI, no hotspots but soft corners and not as sharp as Sigma 50 Art.
    – Sigma 10-20 f/4-5,6, no hotspots, soft and as with other lenses, corners are sharper when zoomed in.
    At first I made custom WB using Tamron 10-24 VC, but when I use Sigma lenses with that WB preset there is slight orange tint, I don’t know how else to explain this, pictures are slightly more flat in contrast compared to those made with Tamron 10-24. When I made custom WB preset for Sigma lenses it was much much better, but Tamron is better again when using the same WB preset, it’s like IR response is much better with that lens. Nikkor 18-55 and 50 AI are as good as Tamron, good IR response and great contrast. Basically if lens 1 is better then lens 2, this behavior translates to IR as well, at least when it comes to sharpness. I was astound when I realized just how sharp Sigma 50 Art is in IR.

    1. Did you try the Sigma 50 Art at all apertures? It’s listed in the Poor Performer for hot spots column.

  44. Hi.
    I Can repport that Samyang AF 35mm F1.4 FE(Sony FE mount) has a severe hotspot.

    1. At least with a 950nm filter on a non converted Sony A7II camera.

  45. I can also repport that the same goes for the Sony FE 85mm f1.8. Hot spot on all apertures.

    1. I actually bought the FE 85mm 1.8 (not quite for landscape IR purposes) and can testify it actually works pretty well. Made a session with it during sunset, and seem to be OK with very mild hotspot at f/14 and beyond. IMHO f/14 is not the most common use case. So perhaps there are different batches or something. SEL85F18 is the model I have.

    2. Tried it at f8, it’s I think the worst hotspot I’ve ever seen on any lens at that aperture. This is on an APS-C A5100. Shots do seem usable in black and white, but in color it’s absolutely atrocious. After RGB-BGR channel flip there’s a massive yellow stain in the middle.

  46. Hot spots noted with Sony 16-35mm f2.8 G lens at above f8; same with Sony 24-105mm f4 G lens & with Zeiss 18mm f2.8mm lens. What a dissappointment.

    1. your post about the 24-105mm f4 G lens is a bit confusing. you say hot spots with Sony 16-35mm f2.8 G lens at above f8… does that mean hot spots also start on 24-105mm f4 G at f8? thanks in advance

      1. Yes. Same.

  47. What about the Fujifilm XF 16-55 f2.8 ? Is it a good performer or a poor performer with regard to IR hotspots?

  48. Hello,

    I tested the IRIX 15mm f / 2.4 lens on a nikon D610 FS and there is an important hotspot in the center whatever the setting f/

  49. What about “FE 70-300 mm F 4.5-5.6 G OSS SEL 70300 G”?

  50. I am looking at getting the Samyang 16mm f2 lens, has anyone had experience of this for IR

  51. I rented two Sony lenses last week to use with a newly converted Sony AR7III Camera
    I had issues with a 24-240 lens before I had consulted your data base.

    I found the Vario-Tessar T FE 24-70 F$ ZA OSS Lens to perform well as listed in your data base.

    I had wanted a little longer reach so I also tried (rented) the Sony FE 24-105 G OSS Lens also
    This lens should be added to your poor performer list for Sony as it had the hot spots at every setting
    It looked to me like F4 at 105 mm was the only usable setting.

    1. Hello Denns.. I read your article and I think you can get me out of my doubts: I Wanted to buy a Sony A7R II to modify it to full spectrum but I saw in the page of Shop kolariVision… “WARNING: This camera contains an internal diagnostic IR Led. This can cause light leaks when using very long exposures and high ISOs in the H-alpha and IR enabled conversion, in the range of 30 second exposures at 6.400 ISO. Can also have fine horizontal artifacts across the frame in highlighted areas in the IR enabled conversion due to the different sensitivity of some rows of pixels. “… This same text says for the Sony A7 RIII and I would like to ask if the “fine horizontal artifacts ” are greatly appreciated and if they really affect the sharpness… Thank you

  52. Zeiss F-Distagon 16 mm C/Y on Canon 5DII full spectrum. Custom converted lens version with internal UV, 590, 720, and 1000 nm filters. Good performer, but with 1000 nm filter the lens does not focus to infinity. However with a bit of stopping down (f/8) the infinity focus is essentially at the hyperlocal distance, so still works. No hotspot even wide open. Extreme corners are a bit softer, as expected from a rectangular fisheye.

  53. Zeiss Otus 55/1.4 ZE. Great performer also in IR.

  54. Could you recommend IR suitable lens from m42 mount? I love my Helios 44-2 58/2 but wasn’t able to find reliable feedback how this lens works with IR filer. But I’m happy to try other m42 lenses if you recommend some 🙂 .

  55. Excellent resource, thank you! The Tamron 24-70 versions are missing, my most used lens. How does one test this best? I could contribute my results.

  56. I wan to convert Fujifilm’s X70 Camera to 830nm. Has anyone got practical experience on this, regarding IR Hotspot by its native lens (Fujinon ASPH Super EBC 18.5mm f2.8)?

  57. Anyone tested Laowa 15mm F2?
    Is there any hotspot starting from which aperture.

    Kindly share.

  58. The Kamlan 50mm f1.1 works quite well. no hot spot.

  59. I looked at the Nikon list, and I found some funny lenses:
    Nikon 70-80 mm f/4.5-5.6 ED AF-D VR Micro NON EXISTENT!
    Even if ve corrected the focal length to 70-180 mm, there would still be an extra VR (70-180mm Micro-Nikkor has never been produced in the VR version)

    Then, you have a triple listing of the 85mm PC Micro
    Nikon 85mm f/2.8 PC Micro
    Nikon 85mm f/2.8 PC-E Micro
    Nikon 85mm f/2.8 D PC-E Micro

    Probably should boil down to two, at least if we give credit to Roland Vink’s Nikkor Lens Version Database
    Nikon 85mm f/2.8D PC Micro
    Nikon 85mm f/2.8D PC-E Micro
    Both lenses communicate the distance to the body via the contacts, the more recent one has an Electronic Aperture control.

    And then there’s this one:
    Nikon 105mm f/2.8G AF-S VR IF-ED
    For consistency with the rest of the list (all other micro Nikkors are marked as such), it should read
    Nikon 105mm f/2.8G AF-S VR IF-ED Micro

  60. I have a Canon 5D Mark III that’s converted to Kolari 850nm monochrome and was looking for a substitute for my Sigma 50 Art. I bought the Canon EF 50mm f/1.8 STM and I haven’t had any issues with it. I also use it on my non-IR Mark IV bodies with great success. It’s surprisingly good for $125. 🙂

  61. I converted a Sony NEX 5N with SEL1855 that I got on Ebay. Full spectrum conversion and mostly I use IR720 and IR680 filters. At first I thought SEL1855 was performing, then over time I realize it is one giant hot spot at F 3.5 in most cases. You can dial the hot spot from giant covering 2/3 screen from center down to a bright pinpoint at F22. Most daylight shots are highly problematic. You won’t notice sometimes then you look when you get back to the computer and you realize there is a huge brightened circle of light distorting the image. You can avoid the hot spot and make it work on some angles, but when it gets in the way during daylight photos you will have very difficult time. I would suggest a follow up and review this lens again because I have had to look for alternatives and have many many photos with the large glow of the hot spot which is more like a giant hot circle.

  62. I remade the fuji xe-2 into a full spectrum. I started having problems after Canon. No lenses! Almost everyone gives a hot spot. Samyang 12/2, Fuji 16-50, Fuji 18 / 2.0 can be used – up to 2.8, 18-55- always a hot spot, Fuji 55-200- ok is always. Sinma 10-20 / 4-5,6 – always a point (starting with a blurred). Canon 17-0 and 18-105 – no until 11!
    What is sigma 10-20 / 3,5 ?????????
    Tell me the 10-12-14 mm wide corner !!!!!!!!!!!!!! for fuji.
      Vladimir, Russia.

    1. I use Sony A6000, the full spectrum. Tamron 10-24 does not give Hot Spot at all. This is the most suitable lens that I came across! Recommend.

  63. Hello!

    Sigma 10-20mm f / 3.5 EX DC HSM ELD SLD (flares, but ok with hotspots)
    to is the IR range? What it is? Does the lens work or not?

    Vladimir Proshin

  64. Hello.. Please.. I can recommend zoom and fixed targets for the Sony a7r II that you have security that do not produce Hotspot…?
    And Tamron 28-75 mm F/2.8… What do you know?

    1. I tested the Tamron 28-75 ƒ2.8 Di III. I didn’t observe any problems.

  65. Jupiter 9 has no infrared hotspot at any aperture but I tested with speed booster lens.

  66. Hi, I don’t see the Nikon 28-300mm f/3.5-5.6 VR on the list, anyone used it for IR. Any hotspot problems?
    Thanks in advance.

    1. Lee, did you get any feedback on the Nikon 28-300 VR? I seriously want to get one for my walk around IR shooting. I suspect it will be like my other better Nikon Zoom lenses… good into you stop down past f/8. I could live with that.

  67. I would like to add to the Fujifilm X lens list another poor performer, the ZEISS Touit 32mm f/1.8 Lens for FUJIFILM X. Sadly, hotspot on most all apertures.

  68. Fuji 35mm f2 gave me some color shift in the middle at f5.6.
    Fuji 15-45 works ok. Start to see mild hot spot around f8.
    Tested on x-t10 full spectrum converted with 590nm/720nm

  69. Slight hotspot on Sony Planar T ZA SSM SAL50F14Z at f/8-f/16.

  70. the Nikon 50 mm f/1.4 AF-D listed in the good column has a mild hotspot at f/11.

    1. How about its performance between f2.8 and f8.0 compare to the best fifty you have test so far?Thanks!

  71. After seeing the Minolta 50 f/2.8 AF Macro in the Good column, i got one. It’s sharp but when shooting landscape scenes at f/11, you can see a mild but noticeable hotspot (warmer and brighter) in the center. I’ll keep it for my other color camera (A99ii).
    I reconfirmed that the Minolta 50 f/1.7 has no hot spots at f/11. color and brightness are even, even when channel swapping. Although, sharpness is not as good as the 50 f/2.8.

  72. Has anyone tried Kaxinda 25mm f/0.95 ? the reviews for normal use is good, and it’s quite cheap – 175$ brand new. So i wonder how is it for hotspots

  73. Has anyone tried Kaxinda 25mm f/0.95 ? the reviews for normal use is good, and it’s quite cheap – 175$ brand new. So i wonder how is it for hotspots

  74. Tamron 45mm SP f/1.8 Di USD – mild hot spot at f/5.6 and gets very noticeable at f/11-f/16. one of the sharpest lenses i’ve used-too bad it doesn’t work well for IR.

  75. Has anyone tried Laowa venus 9mm F2.8 zero-D ???

  76. Hallo
    Ich weiß nicht,ob ohne “Hotspot” oder?
    Nur neu Nikon AF-S Nikkor 16-80mm F2. 8-4.0 E ED VR 72mm???
    Aber nur sehr gut frei “Hotspot”
    Alt nur Nikon AF-S DX Nikkor 16-85mm F3. 5-5.6 ED G VR 67mm!

    Pierre Rechenberg

  77. Has anybody tested the new fuji 16mm f2.8 WR ?

    1. Just looked at my set of test files again and I see no hotspots throughout the range of the 16/2.8 WR. Anecdotally, very happy in use along w/ 23/2, 35/2 & 50/2 WR on X-Pro2 converted to 665nm by Kolari. Limited use of the Laowa 9mm owned by a friend, but nothing jumped out me as an issue. HTH.


  78. I am planning to have an A7r modified. The information I find in google searches about lenses, however, is inconsistent. I have the Sony 55mm, and it seems to be generally agreed to be excellent at all apertures. I also have the Sony 16-35 (f4) and the 35mm (f 2.8), about which there are conflicting reports. I would like to have a native Sony mount lens, probably 35mm or 28mm but possibly 24mm that has no problem at any aperture. I am looking for a smaller lens (the Sony 35mm, 1.4 is a monster). Something like the Sony 35, 2.8, without the reported limitation. There is a report at Lens Rentals that says the Zeiss lenses are good, but it does not give specifics. If it is good for IR the Loxia 35 would be excellent.

  79. Tamron 24-70 is awesome btw.
    I did not see it listed. Of all the lenses that I own, the 24-70 is the only one that works best for Ir. No hot spots even stopped down, and no issues to report whatsoever.

    5d4 + 24-70 + Ir filter 720nm

  80. Does anyone has experience with the Tamron 28-75 mm f/2.8 Di III RXD ? In the DB earlier releases marked as bad performers.

    1. I tested it on the A7 @ 850nm here: It performed better on APS-C however, perhaps because it doesn’t look like a traditional hotspot.

  81. Nikkor AF 50mm f/1.4 D hotspots in some scenes starting at f/5.6 and beyond (tested on NIKON D7100 590nm Kolari filter)

  82. Nikon Z7, FS (AR/AS) conversion, 850nm AR Kolari filter:

    Nikkor S 24-70/4: outstanding to f/11. Central hotspot thereafter. All focal lengths are good.

    Nikkor S 24-70/2.8: acceptably mediocre at 2.8 with diffuse, mild hotspot. Unuseable beyond f/4. Focal length is irrelevant.

    Nikkor S 14-30/4: outstanding to at least f/11. Never use the lens beyond that. All focal lengths are good.

    1. Mike, I wanted to add my observations using a Z6 and the Nikkor S 24-70/4… First signs of hotspots was at f/10 but was almost invisible and did not really change until f/16. And pointing the camera in some directions (as to where the sun was), I saw no hotspots at all even at the smallest aperture.

    2. Also, I do have some information on the Nikkor Z 50 1.8 S lens. It followed almost exactly the same pattern as I observed with my Nikkor S 24-70/4. Hot spots stated at f/10, but was almost invisible and did not really change until f/16. And in certain angles from the sun, I saw no hotspots at all in any aperture.

  83. hI
    I’ve tried the Olympus 12 40 Pro with EM1 II and Hoya 720 filter : BAD PERFORMER ( Hot spots)
    Panasonic Leica 8 18 : GOOD PERFORMER ( Clean picture and NO hot spots)

    1. My 12-40 PRO also exhibited bad hot spots at f/5.6. I am going to try it wide open to see if it is usable.

    2. i have the 8-18 Panaleica and it’s the best ultra-wide zoom for m4/3 i can find so far. although, there is a huge mild warm spot you’d only notice if you do faux color processing. i have been fixing it in photoshop and it’s less noticeable if you use a 590 or 665nm filter (instead of a 720).

      if anyone knows of an ultra wide zoom for m4/3 that’s relatively sharp with no need for post process fixing of hot spots at any aperture and any focal length (a lot to ask for), please let me know.

  84. Fujifilm XF 23mm F2 R WR: An excellent performer, I’ve never encountered hot spots under normal shooting conditions. This is my default lens for most IR situations.

    Fujifilm XF 50mm f/2 R WR: The best performer WRT hot spots on X-mount in my experience. You may be able to force one artificially but I’ve tried and have failed thus far.

    Fujifilm XF 14mm f/2.8: I was getting mild IR hot spots / halos as low as f/5.6 and returned it.

    ZEISS Touit 12mm f/2.8 for Fujifilm X-mount: An excellent performer that I bought to replace the XF 14mm. This is now my primary wide angle lens for IR.

    1. Are your test done on a full spectrum converted body. Particularly interested in your comments on the ZEISS 12mm

  85. For Sony E mount (i.e. APS-C):

    – the Zonlai 22 mm f/1.8 appears to have no hotspot, at least shot at f8. Hyperfocal setting for infrared at f8 is to set the focus ring at 1 m (~3ft), and the results are then acceptably sharp to me. For landscape and general city shooting, I basically just do this and don’t even bother to check focus. Manual focus at closer distances and with wider apertures provides detailed results as well (e.g. portrait). I was planning of getting rid of this lens, but it’s now my favorite for IR. It is a bit prone to lens flare though in situations where the sun is positioned very unfavourably.

    – the Sony 35 mm f/1.8 has no hotspot, is sharp and works fine. I mostly don’t use it for IR on account of it living almost full time on the regular camera.

    – the Meike 6.5 mm f/2.0 fisheye is basically unusable, as it doesn’t seem able to achieve focus for infrared.

    – the Samyang/Rokinon 12 mm f/2.0 NCS CS has a pretty significant hotspot (tested at f8). It is otherwise sharp. Hyperfocal setting at f8 for infrared is to focus just left of the “0” in “0.5 m” on the focus scale.

    1. I have tested the Sony 35mm f/1.8 on a full frame Sony (A7 & A7III) @ 850nm and it was really bad. Unusable throughout the range:
      There could be a difference on APS-C (I have seen that before), but for me this lens is worse than the Sony/Zeiss 35mm f/2.8 which is already notoriously bad.

      1. I should clarify my comment was about the SEL35F18 (the crop lens of 35mm/1.8), rather than the SEL35F18F (the full frame lens with the same specs).

  86. These are my results regarding hot spots for lenses not in the database using an Olympus E-M5 with an uncoated 720nm conversion.
    Poor performers: Olympus 8mm f1.8 fisheye
    Decent performers with mild hot spots: Olympus 12-40/2.8, Laowa 7.5mm f2.0, Olympus 12-50 f3.5/6.3
    Excellent performers: Olympus 9mm F8 fisheye body cap (pronounced soft edges), Panasonic Leica 100-400 f4.0-6.3.

    1. Thanks for the tests. I have also gotten hot spots with the 12-40 but have not tried it at all focal lengths and apertures yet. I am awaiting filters to test the Laowa 7.5. Did you shoot all your lenses wide open or if not, at what apertures and focal lengths?

  87. Hello,
    what about the IR capabilities of the new Fujinon XF16-80 f/4 lens? Is that usable for infrared photography?
    Kind regards

  88. Hello People!
    Found a new favorite and it’s working great for infrared.
    Tamron 35-150 2.8/4
    I was able to test it finally. Happy to report that no hotpot issues encountered so far. I did some quick tests at different focal lengths and upto f8, and was not able to produce any hotspots.
    So yep this is my second lens that works great for infrared.

    Hope this helps!

    1. I have the same results, except for the 830nm filter at 35mm.

  89. Tamron 17-35mm f/2.8-4 DI OSD at f/5.6 on Nikon D810 with 82mm HOYA R72 IR 720nm: no hot spot. Didn’t test at smaller apertures. f/2.8 @17mm and f/5.6 @35mm being the sharpest apertures for this zoom lens.

    1. Thank you very much for the information!

      I’m going to buy it for the modified Nikon Z6 at 590mn

  90. I tested the Tamron 28-75 ƒ2.8 Di III. It’s a good performer; no observable hotspot across the zoom range at ƒ11.

    1. Anyone try the 17-28 ƒ2.8 Di III?

  91. Hello all,
    Just a note to all of you about lenses. Lens manufacturers attempt to make the same designated lens consistent over time, with the transmission of visible light.
    The lens manufacturers have to buy glass, grind the glass and in most cases coat the glass with various
    coatings. Glass produced by different glass companies can vary in composition, current production and over time. The lens makers work with various coating materials that can change over time.
    Then the lens makers tweak lens elements, such as using optical plastics in newer versions of any designated lens. On top of all that change, manufacturing tools, jigs, and testing equipment wears in use. A lens made and tested on new equipment can be slightly different to the lens made on the older equipment. What that means is each of the lenses will be within designed tolerances, but different nevertheless. Cheaper lenses can be as sharp and as good a performers as expensive professional lenses. But they also wear out faster. The various gears, cams, aperture controls, etc.,in any lens wears over time. These components can be metal in an older lens, and plastic or engineered polymers in newer lenses.Plastic doesn’t necessarily equate to bad. And then then we have the greases used in the lenses. Grease thickens or hardens over time. For instance Nikon greases stand up over time and Leica grease has to be dug out and replaced every 20 years or so.
    There are optical companies that make lenses for a large number of different camera makers and lens re-sellers. So the same lens can be sold under different brand names.
    On top of all that, the lens makers are trying to eliminate the transmission of UV and IR light and improving the transmission of visible light.
    So you are trying to make a lens do something that it is designed to NOT do.
    Taking into account all the variables involved, of course some lenses show “inconsistent” results in IR and UV testing.
    What that all means is that any copy of any lens can vary in almost any test or application.

  92. Voigtlander 65/f2 macro for Sony E mount has hotspot starting about f5.6

  93. Has anyone tried the Zeiss Loxia lens, are they compatible with IR, or do they also have problems with hotspots.

    1. I have tested the 21mm (terrible) and the 50m (not too bad). I wouldn’t recommend either however since the Sony / Zeiss 55mm f/1.8 is far better for IR than the Loxia 50mm. I’m still curious about the 85mm because I would like a native mount IR lens in the focal range that takes 49mm filters. You can see detailed examples from the two Loxia lenses here:

    2. I can’t understand the loxia 21mm score. Of course, it appears if it is F11 or higher, but it is useful until F8. Also, the resolution itself is really overwhelming.

  94. Hi,
    I have been using the Nikon 24 – 120mm 3.5 with HOYA R72 filter and when used at f9 there is no hotspot. I bought the Nikon 20mm 1.8 specifically for my Infrared photos as I wanted a sharper lens and Im yet to find an aperture that eliminates the hotspot. Im very disappointed and will now need to sell the lens. I do however own a NIKON 14mm – 24mm 2.8 lens but because my camera is not converted to IR so I need to use the Infrared filter. I have not been able to find a filter to suit anywhere. Does anyone know a solution for this. NISI and NEEWER don’t make the infrared filter and would this work anyway? Any advice???

  96. Results from a quick test on a Fujinon XC 15-45mm. X-E1 full spectrum and Zomei filters. At 15mm with 720nm and 950nm no hotspot until f22. At 45mm with 720nm hot spot starting at f16 and with 950nm starting at f11

  97. I have tried the Sigma 17-50mm f/2.8 EX DC OS HSM Lens and it suffers rather badly produces large hotspots. I would avoid this lens for IR.

    1. Mine is great at 830 and f8 on a Nikon D700. It is my go to lens for WA. I have not tried it at 720. Some images show a very minor hotsot at f8

  98. Since I couldn’t find info on these I got to test two newer lenses at a store today and can report on performance (this is on a new full spectrum conversion with pro AR coating on an A7R IV). New Sigma 24-70 f2.8 DG DN lens for sony (l mount is the same): Poor IR performance and noticeable hotspots above f10. It could be worse at lower apertures too I was only looking through the viewfinder outside the store so it was hard to tell, but it was clearly visible at f10 and up so probably not great below either if I had a better environment to test/review. Interestingly my sigma 14-24 DG DN is better for IR from the quick tests I’ve done, but limited to cutting gels in the back.

    The tamron 17-28 f2.8 for sony was excellent and no noticeable hotspots just like the tamron 28-75 I already have. This lens I will buy soon.

    1. have you noticed any banding at all with your a7r iv? what other lenses have you found that work well

  99. Today, I Tested sony a7R3 + SEL20F18G.
    Unfortunately, this is poor performance.
    Sadly, there are no alternatives, so we will use them until a replacement lens Discover.

  100. Does anyone has experience with the Zeiss Milvus 15 mm 2.8? I’d like to buy it for my Nikon D810.

    1. Finally I tested the lens yesterday in a shop with a Hoya R72 and my Nikon D810. With an open apperture there is a slight hot spot, but with smaller ones (I tested 8 and 11) it gets impressive. At the end I didn‘t purchase the lens.

  101. Has anyone heard how the Fujifilm 16-80mm f4.0 does in Infrared?

  102. I just received the new Sony FE 20mm f/1.8 G lens. Bought it for night photography, and checked it also on my Sony A7iii with 590nm IR. Bad hotspot clearly noticeable after f/4. Without overly processing in post, f/4 is the last useful aperture.

  103. Has anyone tried any of the Panasonic S lenses for the S1R?

  104. Has anyone tested with the Panasonic “S” lenses (16-35, 24-105, 70-200 f4)?

  105. I definitely need to contribute too 😉 Here are the lenses I have tested:
    – Nikon 85mm f/1.4G (model 2195)
    – Nikon AF Micro-NIKKOR 200mm f/4D IF-ED (model 1989)
    – Nikon AF-S NIKKOR 300mm f/4E PF ED VR (model 2223)
    – Rokinon 20mm f/1.8 ED AS (model RK20MAF-N)
    – Samyang 24mm f/3.5 ED AS UMC Tilt-Shift (model SYTS24-N)
    – Sigma 50mm f/1.4 DG HSM Art (model 311306)
    – Sigma 135mm f/1.8 DG HSM (model 240955)
    – Tamron 17-35mm f/2.8-4 DI OSD (model A037N)
    – Tamron SP 35mm f/1.4 Di USD (model F045N)
    – Tamron 35-150mm f/2.8-4 Di VC OSD (model A043N)
    – Tamron SP 70-200 f2.8 Di VC USD G2 (model A025N)
    – Tamron 90mm f/2.8 Di VC USD Macro (model F017N)
    Each one combined with these IR filters:
    – 830nm (Deep B&W IR)
    – 720nm (Standard IR – Hoya R72)
    – 590nm (Super Color IR)

    1. keep getting a 404 error

  106. Tested the Rokinon 24mm f/1.4 ED AS UMC (model RK24MAF-N).
    => Not suitable for IR

  107. Tested the Nikon AF-S NIKKOR 16-35mm f/4G ED VR.

  108. you can use an auto-focus adapter and put a different brand lens on (like a Nikon 17-35 f/2.8 on a Sony A7R3).

  109. Tried a few lenses on an APS-C Sony body converted for 720nm. Keep in mind that all but one of these lenses is for full frame, and I’m accounting for that. Results:

    — Sony E 18-55mm f/3.5-5.6 OSS: Hotspot is way worse at 18mm than the chart says. Hot spot starts to become visible at f/5 and is definitely visible at f/5.6. Fine at other points in the zoom range.

    — Samyang/Rokinon AF 35mm f/1.4: Fairly noticeable hotspot starting around f/4.5 to f/5. Fine wide open.

    — Nikon 80-200 f/4 AI-s: Didn’t notice any hotspots at any point in the zoom range at any aperture.

    — Nikon 300mm f/4.5 AI-s (the non-ED one): Completely useless on APS-C. Not sharp at all wide open and diffraction kicks in before it can be stopped down enough to be useful. May be useful on full frame, but I don’t have a converted full frame camera to test it with. Didn’t notice a hotspot though.

  110. Recently used a EF 24-70mm f/2.8L II USM mounted on a 590nm converted 6D. Hotpots were evident starting at f8 and clearly intensified with each stop down. Even at f/8 I had hotspots on some images where ISO and shutter were adjusted for uneven ambient lighting. Just as noted in the Kolari database, this lens is a poor performer.

  111. I tested on a full specturm X-T2 and no problems

  112. Can you show us the pictures with the tamron please?

  113. The Sigma 16mm f1.4 DC DN Contemporary for Sony E mount has a huge hotspot at f8. Not tested at other apertures.

    1. Hi, what infrared nm rating were you shooting at? 720, 830? Are you able to post a link to some sample images? Thanks!

      1. 590nm. It was bad enough that I deleted the pictures in-camera and I won’t have the lens available for several months I’m afraid.

        1. Thank you. Appreciate the reply. I ended up getting a Zeiss Sonnar® T* FE 55 mm F1.8 ZA lens which is great for IR. Still looking for a nice wide angle that is just as great.

  114. I am overall pleased with the Tamron 17-28 f/2.8
    I notice some magenta in the vignette corners when using with 590nm and 720nm. On the 850nm the issue is not present or I haven’t noticed.

  115. The Kamlan 28mm f1.4 shows a hotspot from f5.6 to f10. I’ll try it further in more scenarios.

    1. At f1.4 is passable, but the hotspot is visible throughout the whole range

  116. i agree with Steve on the Olympus 12-40/2.8 and will add more specifically, mild hot spots starting around f/8 at 12mm, difficult to correct by f/11. so mild that you may not notice them unless you do faux color processing.

  117. anyone test the new Olympus 12-45 f/4 Pro lens?

  118. I know it’s a long shot, but I really want to know if Fuji’s 2020 updated 10-24 (the WR version) works any better with IR. The original has always been my favorite visible-light landscape lens, but the hotspot is so harsh, it’s unusable at any focal length shorter than 24mm.

    1. Same here. The original is an excellent IR performer:
      for several samples.

  119. Tamron 17-35mm f / 2.8-4 Di OSD
    is this lens good for IR?

  120. Anyone know if the Fujifilm 16/80 F4.0 is Good Hot Spot wise? Thanks ….

  121. Do the hotspot happen only when doing IR? I have a full spectrum and I am planning on getting a hot mirror filter, but wanted to know if I would experience the hotspots when doing Visible Spectrum photography?

    1. When you shoot visible with the hot mirror, you will no longer get hotspots. They are an IR only phenomenon.

  122. Hi, has somebody experienced VILTROX 23mm f1,4?
    With my D800 Full Spectrum I use old Nikon lenses (Ais) 28mm shift, 35mm shift, 85mm f1,4 and 105 f 2,5 with no hot spots, expecially in wide apertures; bad use sigma 24mm 1,4, Nikon 85mm f 1,8 AF (sold!).

  123. I’ve successfully tested a Zeiss 50mm Planar T* F1.7 (Contax) at all apertures with no hotspots on a Canon 60D Full Spectrum at 720nm
    (Same test shows significant hotspots on Canon EF 50mm F1.4 which is already in Database)

  124. Has anyone tried out the new Sony FE compact primes for hotspots? The 24mm F2.8 , 40mm f2.5, and the 50mm F2.5?

  125. Anyone has ever tested SONY SEL18135 (Sony E 18-135mm F3.5-5.6)?
    Thanks a lot!!

  126. i bought the new Olympus 8-25 f/4 Pro for my color camera but tested it on my full spectrum w/720nm IR filter. it has hot spots, very large, even, warm, all apertures , real bad over f/7.1, mostly correctable post processing.

  127. i’d like to add that i just got an olympus 14-42 II R which shows as a good performer, but don’t agree it’s “good”. there’s a mild correctable hot spot w/720nm filter at f/8, only noticeable when doing faux color processing. you’d never know if you were doing monochrome IR processing.

  128. My assortment of lenses falls somewhere between substantial and “all of them”. And I’m very picky about hot spots. I have rejected dozens of lenses listed in the “good” column above. Like I said, I’m picky. So far, I’ve found seven lenses that show only the faintest hot spot photographing a black subject in the middle of a bright field with the lens stopped down AS FAR AS IT WILL GO. Usually f16 or f22.
    Those seven are……..

    20mm f3.5 Nikon UD. (Their first 20mm) Much better than the 20mm f2.8 Ais.
    28mm f3.5 Nikkor-H Pre Ai. Much better than the 28mm f2.8 Ais, an Emarit M, a Zeiss Distagon, and five others.
    35mm f2.5 Canon FL. Just about perfect. Easily beat eight contenders including several listed in the “good” column.
    40mm f2.8 Canon STM. Just about perfect.
    50mm f1.8 Canon STM. Easily beat a whole bunch of other 50’s including several Nikkors, a Planar, and a Summicron M.
    57mm f1.4 Hexanon AR. Nearly perfect. An exceptionally clean lens.
    58mm f1.4 Minolta MC Rokkor-PF. Just as near perfect as the Hexanon.
    85mm f1.8 Canon FD SSC. Not perfect, but very good and better than Nikon f2 Ais, and the Nikon f1.8D.

    Will report more as I find them, but these are all EXTRAORDINARILY resistant to flaring issues at all f stops.

  129. I can’t believe my favourite IR lens is not listed 🙂
    Sony FE 28-70 f3.5-5.6 has no hotspot at all. I’ve used it on my Full Spectrum A7II and I can’t recall that I ran into hotspot like ever.
    Unfortunately can’t say the same from the Sony FE 24-105 F4 which is quite a bad performer :'(

  130. Any word on newer wide angle Canon RF options? (Especially interested in the RF 16mm f/2.8 STM, RF 14-35mm f/4 L IS USM, Laowa 14mm f/4 FF RL)

  131. I have used the Olmpus OM 55mm f1.2 with B+W 092 with good results even at f/1.2
    also, the Arstat 20mm f2.8 with B+W 092 with good results
