I bought this lens to use my Canon glass on a Fuji XT2. Overall, the adapter works well with a 17-40mm, 100mm L macro and the 100-400mm L (v1). Overall, as a stop gap measure it worked fine. Given some of the negatives listed below, I may sell most of my Canon lenses and keep this to use with my Macro lens.What worked:- The adapter is solid, and mounts well to the camera and lens- There is no problem with controlling the aperture electronically- Autofocus will workWhat doesn't work:- Autofocus is quirky. The lens will reset its focus when trying to adjust.- Your lens will continue to reset the focus, even when set to manual focus on the lens.- It is difficult to get infinity focus on longer lenses.- Canon IS does not seem to work- Lightroom will only ... MoreI bought this lens to use my Canon glass on a Fuji XT2.

This is a minor issue.

The big issue with this item is that it does not allow autofocus communication. Whatever lens is attached the ultrasound motor on the lens will continually search back and forth. Not good.

Great product for Ex Canon users
I'd love to review this better. It's a pretty simple device and very well made. Feels solid. But, beware, if you have an X-T30, it is not entirely compatible. It works if you enjoy odd IS behavior and only manual focusing. The behavior of autofocus was odd. It would act like it was focused, but only seldom would it engage the motors to do so. And the camera would indicate focus even when the image clearly wasn't focused. All of my lenses were on the compatibility list, but less apparent was the compatibility list for cameras. Only upon emailing their support did I find out it wasn't compatible. So, back it goes. I'm trying the Fringer next. It claims compatibility on all of my lenses and the X-T30. Fingers crossed. Sadly, I'm not inclined to ever purchase a Viltrox ... MoreI'd love to review this better. It's a pretty simple device and very well made. Feels solid.

Sadly, I'm not inclined to ever purchase a Viltrox lens now because I don't know if it'll work properly with my body.
Cannot get f1.8 for sigma art 18-35.Only gets up to f4. With Fuji XT3
My adapter stopped working in three months. When it worked it barely worked. This is my 3rd adapter. The company does not respond to emails. Do not buy ANY product from this company
Nice product!
