Canon Ef Adapter For Fuji X

[Yes] This adapter works well on seven Canon EF lenses I use on either the Fuji GFX 50r or 100s. Autofocus is quick and accurate. Some lenses show no vignetting such as the 40mm f2.8 and the 16-35mm f4 from 21-35mm. There is also little vignetting on the 100-400mm ii. Others show more. The ring for aperture adjustment is very handy.

[0.045 lb] I purchased the Canon Mount Adapter EF-EOS R so I would be able to use my older 100-400 EOS lens with my new Canon R5 Mark II. Once it was attached I didn't even notice it was there. There was zero play or movement between the adapter and the lens or camera body. The adapter worked flawlessly while taking thousands of pictures in the Galápagos Islands, without issue.

[Brass] Recently decided to move from Canon to Fuji. Bought a GFX50S and I wanted to use my L glass until I could find a comfortable setup of Fuji lenses. This Fringer adapter was highly recommended for its quality and consistent firmware updates. It works flawlessly so far, and I've been using it consistently for a month now. I've used the EF 16-35mm f2.8 II, EF 24-70mm f2.8 II, EF 100-400mm f4.5-5.6 IS II, and the EF 300mm f2.8 IS. Each lens autofocuses fast (not nearly as fast as natively on a Canon, but that's to be expected with the contrast-detect AF on the Fuji) with no hiccups at all. I would say it is not possible to autofocus the 100-400mm f4.5-5.6 IS II with a Canon EF 1.4x Extender III whatsoever on the Fuji, that probably comes down to the AF of the Fuji. If you're looking to Frankenstein your Canon lenses to your Fuji, then look no further. It's expensive, but entirely worth it.

[4.3 x 4 x 1.4"] This adapter works to mount EF glass on EOS M bodies. Provides all functionality that Canon adapter does but costs less.

[Full-Frame] I purchased this lens for my Canon R6 (with an EF-RF adapter) and really love this lens. It's great for shooting wider for interiors, etc. and blends perfectly with my RF ecosystem. You can hear the autofocus spinning as you move the lens around with AF on, but it isn't a problem - I just couldn't figure out what the sound was at first ;p.

[0.485 lb] I bought this adapter in order to use the Canon EF 100-400mm f/4.5-5.6L IS II USM Lens with my Canon EOS R6 MkII. It works flawlessly!!! It is solid as a rock and there is no noticeable difference between using this EF lens and adapter to using an RF lens with my camera. I don not hesitate to recommend this adapter to anyone.

[0.64 lb] I tentatively switched from Canon to Sony, all three of my trinity EF L 16-24, 24-70, 70-200 lenses work perfectly thanks to this adapter. After this result, the conversion to Sony is complete. I really like the extra firm engagement this adapter provides, it's solid.

[Yes] The Viltrox EF-EOS R works great! just as claimed and saved me almost half off the price the the same adapter from Canon.

[Connector] This adapter only works on the Canon EF-S 18-135 USM lens, which is the newest of 3 versions. (I think this is an under-rated lens. It has a great zoom range, very good IS, its quiet, and low priced. While not perfectly sharp, it is close to the 24-105 and sharp enough for video. I use it mostly on my C 100ii.) If you like this lens, you will love this zoomer. It is well designed and built, and starts and stops smoothly. There is a little bit of noise at the fastest zoom speed, but not enough that my external mike will pick it up. As a bonus, it prevents gravity zoom. A good value at the current price.

[Yes] This lens adapter for Canon EF lenses does not fit on an EF lens. The design doesn't allow it to lock onto the lens. It will simply fall off which makes it unusable.
