The Kolari Vision UV Bandpass Filter for Canon EF-EOS R Adapterfrom Kolari Vision UV Bandpass Filter for Canon EF-EOS R Adapteris compatible with the EF to EOS R drop-in filter adapter from Kolari or Canon. It's designed to work with a full-spectrum modified camera for true UV photography, skin damage analysis, forensic analysis, astrophotography, and other uses. Unlike many third-party UV filters that use interference coating, this one features absorption-based glass, doing away with the problem of inconsistent color across the frame.

The filter has a 50% transmission peak at 365nm, and >25% transmission in the 340-380nm range for high transmission. Average out of band rejection is >OD 4.3 (0.005%), with a minimum rejection of>3.5 OD (0.025%), so there is a high signal to noise ratio and no IR contamination.

The frame is aluminum and the optics are glass with AR/AS coatings. The filter has a wide grip and offers a lanyard attachment point for your convenience.

This filter requires a full spectrum modification to be made to your camera in order to function properly. This entails manually removing the camera's low-pass filter and replacing it with a clear filter. Once that's done, the filter will work as intended. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.)

Q: 5. Will the EF-EOS R adapter functionally increase the F stops of a lens?

A: Short answer: f is not affected. The "original" (unadapted EF lens on a DSLR camera) focal length and opening of the lens are not changed. Long answer: The new RF lens mount has a shorter flange focal distance (distance between rear objective lens and camera sensor) of 20mm compared to the flange focal distance on the EF mount (44mm). The mount adapter is simply a metal tube or spacer that restores the 44mm flange focal distance, so that the EF lens can be used on the RF body.

Q: 7. Im confused by the pricing. Is it correct? All of the adapters appear to have the same base features yet the ones with extra features (eg w/ filters or w/ control ring) cost less than the one without. The basic adapter is $399 while the one with an included polarizer is $99. Thats a lot to pay for less than 1oz less weight. There must be some other difference not described. Can you clarify? Thanks

A: It appears this pricing is incorrect. From numerous sources I've seen, this adapter should be priced at $99.99, with the control ring version priced at $199.99. The two with drop-in filters should be priced at $299 and $399 respectively, with the more expensive version having a variable ND filter vs a circular polarizer.
