Fringer EF-FX PRO II Fuji Canon EF to Fuji X Adapter Autofocus Compatible with Canon EOS EF Lens to Fuji X Mount X-T4 X-T3 XT2 XT20 XH1 X100V X-H X-T X-PRO X-T30

At the time of writing this there are several smart adapters for EF>FX. Pulled the trigger on the Fringer Pro and I'm happy I did. Most of my lenses work well with this adapter, those lenses being: 16-35mm f4L, Tamron 35mm f1.8, 50mm f1.4, 85mm f1.8, 135mm f2L. I can tell you that autofocusing works like it should on most of my lenses and VR works as it should on those that have it. The fit is tight, does not rattle on either the lens or the body. Attaching a lens or the adapter to the camera body both give a very positive and solid click. No fear of something coming undone.Image quality is good. I don't notice any extra vignetting, which is why chose the Fringer over other brands. I don't know how this will affect other lenses so take that for what it's worth to you. All EXIF data is accurate on the camera body and image files.I bought the Pro version of the adapter that has the aperture ring. It works like an aperture ring should, but on a Fuji body it's probably not needed. Not when we can set any button to control aperture. So a lot of you can save yourself $50. The ring isn't too loose, and I didn't find myself accidentally manipulating it.My only concern with the adapter is one I have with most adapters; Weather resistance. There's no sealing or gaskets on the adapter. It makes me wonder what exactly the adapter can handle in wet weather. My X-T3 is weather resistant and so are 2 of my lenses. However, the adapter not being so is something I think about in the back of my mind.I can say I'm not disappointed.

I am using 99.99% of the time my Fuji X-T2 and do not miss the glorious 5D-III. The Canon is now a back-up camera, not because of its quality (superb) but because of its weight and feeling when out taking shots.What I am missing (badly) are the lenses: the 50 1.2, the 85 1.2, the 70-200 f4 and the gorgeous Sigma ART 35mm f1.4 in particular.I tried a manual ring: not good, money down the drain.I was planning to sell all the Canon kit, then I saw the Fringer and decided to give it a try. I was determined to return it in case the AF performances were not decent and in case of any blur/image quality loss.I kept the ring, the AF is not 100% accurate and it varies with each lens (let's say 85% with the 35mm is the worst performance but where it's amazing is with the 70-200 f4 practically perfect). Using the XT2 with the 70-200 is a pleasure, the quality of the shots are superb. It can not match the auto mode of the Canon (I still need to practice and come with final response) but with 300$ I saved a huge amount in Fuji lenses AND my beloved Canon lenses are living a second life. In terms of image quality, I am surprised and can not help recommending the Fringer to whoever enjoys the Fuji cameras and still has one or more dream lens from Canon.

I wanted this adapter to be the king of the Cannon lens to Fuji system problem. I have a decent amount of Canon and Tamron EF/ef-s mount lenses and just recently purchase the Fuji XT4. This seemed like the best solution out there, and is still IMHO probably is. Depending on the lens, the autofocus works decently, which honestly is the same you can say in general depending on the lens you slap on your XT4. I was actually surprised the most by my cannon 50mm 1.4 prime as it auto focused very clean and smooth in video. When you are not recording it is noisy, but the moment you hit record it shuts up and just preforms. My Tameron 24-70 f2.8 vc ii is a different story. Good auto focus for photo, but I wouldn't trust it worth beans for video and it constantly is searching for focus and is noisy. Cool thing is the ability to update firmware through the built in usb port. And is the only adapter that I could find that is actually trying to support video autofocus. MY BIG PROBLEM... not super happy when i first clicked on any of my Cannon glass. There is for sure a slight movement in-between the adapter and the lens. The adapter to the body is pretty solid, but the adapter to the lens there is a tolerance problem. You can feel and tell significantly when manually focusing because you can feel the lens shift every time you go to focus one way to the other which can become very frustrating from a tactile sense. It also just makes you "feel" like it's not accurate or precise.

This worked fairly well when I first bought it to be able to use my Canon 79-300 and 400 5.6 on my Fuji XT3. Problem is, Fringer thought it’s job was done when they wrote the original software that allows a canon lens to talk to a Fuji body. Fuji has had several software updates in the last few years, and Fringer has not kept up. Autofocus, especially on moving subjects, works very poorly and half the time, not at all. So my original investment is worthless now. Fringer support consists of someone responding to your email a few weeks after you send it, and saying they don’t know what the problem might be. Or blaming it on Fuji. I have stopped upgrading all my Fuji cameras, in hopes Fringer will get off their butts and write a new update that will make their product work again. But no luck so far.
