Cameras and lenses generally weren’t designed for infrared use. Unfortunately, as a result, many lenses suffer from an infrared hotspot. We have compiled the world’s most extensive collection of lenses and their hotspot performance. The lists below are based on our internal tests and what others have reported. Lenses noted with an asterisk (*) have had mixed reports or only have a hotspot in limited situations. Please note: even poor performers can sometimes be used. Most hotspots only occur at smaller apertures and specific shooting angles.

Luckily, we offer AR-coated conversion filters that reduce hotspots, improving the performance of the lenses on this list. You can generally expect that with the AR coating, you will get several additional hotspot-free apertures, making some of the poor performers usable.

Please note: This list has errors, or you may find lenses listed as “poor” that you use well. That is because this is a compilation from various sources, and people have different judgements for what is acceptable. For example, a lens with a moderate hotspot at f/10some people may use it primarily at f/6 and below and think it is a fantastic lens. In contrast, someone who uses the lens around f/11 will think it is terrible, while yet another person may use it at f/11 and think the hotspot is mild and can be worked around and still think it’s a good lens. Additionally, hotspots tend to be worse with deeper IR filters, like 850nm, than the color IR filters, like 590nm. 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 them!

After you know what lens is good, order one on Amazon or eBay.

  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.

  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. 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.

  9. 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.

  10. 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

    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.

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

  12. 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.

  13. 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!

  14. 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.

  15. 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.

  16. 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 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.

  17. 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. 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…

  18. 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 ,

    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

  19. 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.

    1. 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).

  20. 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.


  21. 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.

  22. 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.
