The purpose to buy this adapter is to use EF 85/1.2 & EF200/1.8 onto GFX 50R. This adapter works very well, all these two lenses works great on 50R body. Focus fast and accurately, of cause, EF85/1.2 is slower than 200/1.8, but almost the same speed as it is on EOS body.I also tried EF500/4+1.4X onto it, no good for flying birds, but good for big slow moving birds. As birding quites needs cropping, and 50R has high resolution and easier for crop.

I can use my Sigma ART 50 f/1.4 on the GFX100s flawlessly covering the whole sensor. The aperture ring works great, the autofocus is fast and in-adapter correction leaves no need for vignette post processing with this lens,The other lens I tried is the Sigma 14-24 f/2.8 that also works fine and covers the whole sensor at and beyond 18mm. Fringer doesn't have in-adapter correction for the zoom lenses yet though, hopefully they add it in future firmware releases.

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.

I adapted a Tamron 45mm with this adapter; Fringer website said this lens is among one of the officially supported lenses.And the results are amazing. The pictures come with a comparatively fast autofocus (for a medium format), and fringer's in-body vignette and distortion correction makes the Tamron 45mm feel like it's made for the medium format!Caveat: there are some costs to using an adapter. There is a little weight attached to the adapter, and when the adapter is performing vignette and distortion correction there is a little noise. But for the performance I get from this adapter it is excellent for its job--to make lenses like Tamron 45 mm feel like they were made for medium format.
I have used my Fringer adapter for about 3 weeks. I have tested it with my Canon EF 50mm F4, EF 85mm F1.8, EF 28-105mm F4, EF 24-70mm F2.8 II, EF 70-300mm F4-5.6, and EF 70-200 F2.8. Also, I have tested a Sigma 70mm F2.8. All of the lenses work well with the Fringer. Some are slower at focusing but all work fine as far as the electronics. The Canon L lenses and prime lenses work the best. None of the tested lenses cover the medium format sensor. I use the 35mm setting in the GFX 50s II and that setting gives you an 87.7 mb 8 bit/174.4 mb 16 bit file since it is not using all of the sensor. I have the Fujifilm 35-70 lens and the focusing is much better than when using adapted lenses with the Fringer. If you have lots of EF lenses the Fringer is worth getting.
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 ... MoreRecently decided to move from Canon to Fuji.

It's expensive, but entirely worth it.
A bit pricey but overall very worth it, you will need to research which lenses cover the gfx sensor and some have different levels of vignetting and af performance but once the lens is in the supported list you get access to in camera adapter mount adjustment menu to clean up the corners a bit. Also you can't use lens IS/OIS and ibis at the same time but ibis works very very well, allowing you to hand hold the canon 300mm lenses to below 1/60sec easily. The AF speed is something to note, it is surprisingly fast with supported lenses and more so if you have a PDAF supporting camera, the lenses perform like a native GFX lens vignetting aside. If the lens isn't on the list performance is variable, it will work but a very poor performance.But it's not perfect and one ... MoreA bit pricey but overall very worth it, you will need to research which lenses cover the gfx sensor and some have different levels of vignetting and af performance but once the lens is in the supported list you get access to in camera adapter mount adjustment menu to clean up the corners a bit.

Works as expected, for most lenses. I believe fringer has done a good job reverse engineering both Fuji and Canon lens communication specs. However, as expected, The AF, will hunt a little, sometimes kills communication, and doesn't necessarily work with all AF modes, like continuous. Additionally, third party lenses like Sigma, are a bit hit and miss. That being said, a big shout out to the engineering team for trying.Also, a big shout out to the engineering team for the integration of sigma art lenses. They work just as well as Canon, including my very superb, and very hefty. Sigma Sport 120-300 2.8 IS. that makes my day. I really don't want to give up that lens!And for those of you that want the Techart route, you will be pleasantly surprised with Fringer.I ... MoreWorks as expected, for most lenses.

AF could be a little tighter, faster. please figure that one out.
I tried the fotdiox pro, which was not closing the aperture on most of the lens I tried it on. This adapter works on all my canon and sigma lens.I do treat my 100s more like a view camera, so I usually manually focus. It does seem to auto focus just fine. More importantly, it allows you to set the aperture either through the adapter or camera.
I have a couple of EF lenses and a four-year-old auto adapter. The auto-focus always worked slowly. It was ok for scenery but really hard for anything in motion. The old auto adapter stopped working recently and I decided to go with Fringer. The new Fringer adapter has a solid build. And more importantly, the auto-focus is much faster than before. I connected it with Tamron 150-600mm and I am super happy with the focusing speed and image quality.
