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

Although expensive, this adapter does it's job very well. They're really aren't many alternatives that have autofocus and aperture control (which is important on Fuji cameras as most lenses include an aperture control). I'm got this adapter specifically to use with my Sigma 150-600mm f/5-6.3 Contemporary and my Fuji X-Pro 2. It's tough to tell if the OS is working correctly, I hear it activate (btw make sure to deactivate OS on your lens before powering your camera off, I'm not sure if the lens locks back into place by itself when it loses power, so better err on the safe side.) but I honestly can't see a difference, but that could just be me or, camera, firmware, who knows. My only real complaint is that it push/pulls focus pretty drastically if it can't get it on the first try, but at least it's fast so it's not a huge deal. Also, be sure to check if your lens is listed on their compatibility list, I've tried some lenses that are not and it's a little hit or miss, it works but not great on the unsupported lenses. Like I said, there isn't really anything else out there like it, so I still really recommend it.

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.

It does what you’d expect. It adapted canon lenses to my fuji x-t3 without a problem. It was able to run the autofocus and aperture setting as expected. It even worked with a lens that wasn’t on the list (An old 100-300 discontinued zoom). Overall it was pretty nice.A couple things to note. While they worked, the autofocus was spotty. It would sometimes not quite focus correctly. Or it would take a long time to focus. And it made all my lenses super noisy. When hooked up to a canon, the lenses were decently quiet, nothing out of the norm.With the adapter, everything got so loud! The aperture sounded like it was clicking constantly, the zoom almost sounded like it was grinding the motor. It was a bit disconcerting.Again, overall it worked. But as someone just entering photography the cost and didn’t work out in my favor with my canon lenses.

It stopped working after 3 months. You have to send it back to China if you want a guarantee.

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 was a bit hesitant when i first look into this Fringer adapter (never heard of it prior to purchase). I generally do not like mount adapters due to the fact that most do not focus right... most tend to search focus for days, however; this Fringer is the exception...no regrets at all!!!Love the product, it works really well, I mainly do video work and it has no problem keeping focus.I'm using it with 18-35mm Sigma Art on Fujifilm XT-3
