Infrared Drop-in Filter for Canon RF/EF Adapter

Kolari R Drop-in Infrared Filters for Canon EF-EOS R Lens Mount Adapter (EF/EF-S to RF) are made to work with full-spectrum modified cameras to isolate specific wavelengths or create unique artistic effects. Our infrared filters are designed to either completely block visible light—allowing only near-infrared wavelengths to pass—or blend visible and infrared light for specialized imaging. This makes them ideal for fine art, forensic investigation, and a wide range of professional applications.

Each filter is machined from solid aluminum with a wide grip and a lanyard attachment point, offering lightweight strength, secure handling, and user-friendly customization. Our precision-fit attachment system applies just the right amount of pressure, making filter swaps intuitive while ensuring a secure fit during use.

All Kolari R Drop-in Filters for Canon EF-EOS R Lens Mount Adapter (EF/EF-S to RF) feature advanced AR (anti-reflective) and AS (anti-smudge) coatings for improved light transmission, reduced reflections, and easy cleaning.

Please note: Our infrared and ultraviolet filters require a full-spectrum modified camera to produce the advertised effect.

550nm Infrared – Inspired by false-color IR film, the 550nm can produce deep blue skies and pink foliage. This filter lets in more visible light than the 590nm filter and can be used to emulate aerochrome (but not as easily as our IR Chrome Filter) after a channel swap and a few hue adjustments. The unique colors that can be achieved with this filter are perfect for interesting IR landscapes. This filter requires post-processing and is compatible with a full spectrum camera.

590nm Infrared – The 590nm filter can produce vibrant false colors while allowing for flexibility in post-processing. It’s typically used to produce golden-yellow foliage and bright blue skies. This filter requires post-processing and is compatible with a full spectrum or a lower cutoff IR converted camera.

665nm – The 665nm filter can produce vibrant false colors with good B+W contrast. It’s typically used to produce light yellow leaves or the classic white IR look with blue skies. This filter requires post-processing and is compatible with a full spectrum or a lower cutoff IR converted camera.

720nm Infrared – The classic IR filter, the 720nm filter is great for blue sky false color and provides great contrast and dynamic range for B+W. This filter requires post-processing and is compatible with a full spectrum or lower cutoff IR converted camera.

780nm Infrared – The 780nm IR filter creates the classic high contrast B&W IR effect straight out of camera while letting in more light than a traditional 850nm filter. Perfect for B&W IR photography with minimum post-processing, hotspots are also less severe when using this filter. This filter requires post-processing and is compatible with a full spectrum or lower cutoff IR converted camera.

850nm Infrared – The 850nm IR filter creates the classic high contrast B+W IR effect straight out of camera. This filter is compatible with a full spectrum or lower cutoff IR converted camera. It can also be used with some stock cameras with a long exposure.

IR Chrome Lite – The IR Chrome Lite uses both infrared and visible light to mimic the look of the classic Kodak Aerochrome IR film with little to no editing. This filter is only for use with a full spectrum converted camera. Its thin glass design allows it to work behind the lens and achieves richer color than the original IR Chrome.

This filter pairs with a full spectrum converted camera for true UV photography. Read our UV photography articles for lens considerations and general advice for shooting UV successfully. Great for photography, skin damage analysis, forensic analysis, astrophotography, and other uses.

Unlike other UV filters on the market which are interference coating based, we have developed our filters using absorption based glass. The efficacy of interference coatings depends on the angle of incidence, meaning that transmission characteristics change depending on the angle of the light rays. This may be fine for use with a telescope, where there incoming light is very parallel, but for general photography this causes problems with inconsistent color across the frame.

Our filter has a 50% transmission peak at 365nm, and >25% transmission between 345-380nm for high total light transmission. Average out of band rejection is >OD 4.3 (0.005%), with a minimum rejection of>3.5OD (0.025%), meaning there is a high signal to noise ratio and no IR contamination. Our UV filter is coated for durability. Uncoated UV glass is sensitive to oxidation when exposed to humidity, ruining the filter. Due to the thickness of the glass, the filter is only threaded on one side only.

*UV photography requires a UV-compatible lens*

The Kolari EF-EOS R Drop-In Filter Mount Adapter is compatible with the Canon EOS R, R5, R5C, R6, R7, R50, R100, RP, RED Komodo, RED Komodo X, and RED V-Raptor. All of our Drop-In filters are compatible with Canon’s Drop-In adapter system as well as our own.

Please note: Our infrared and ultraviolet filters require a full-spectrum modified camera to produce the advertised effect.

Our filters are thickness matched to minimize focus shift, EXCEPT for the IRChrome and UV Bandpass. These two filters need to be thick by design, which can reduce macro focus range, and can reduce corner sharpness on wide-angle lenses. In our tests, the effects were fairly minor, however.

We understand that post-processing IR images can be challenging at first but don’t worry, we have many resources and tutorials available for IR photographers. Here are a few of our most popular IR post-processing resources below:
