Review on Fotodiox Pro Fusion Smart Adapter: Seamless Compatibility between Canon EOS EF/EF-s Lenses and Sony Alpha E-Mount Mirrorless Cameras by Colin Zilinskas

I've had the adapter for a few months now and am very happy with it. Looking at some of the other reviews I can say that I've never had a problem with the adapter losing connection between the lens and the camera. The aperture setting on my EF 24-105mm L worked flawlessly and consistently. Build quality is generally what I need. It doesn't seem too cheap and I'm not worried about my lens. It should be noted that the autofocus sucks. It works, but if you really need autofocus I'd recommend just saving and getting the meta bones. I mostly focus manually myself, so it doesn't really matter whether autofocus works well or not.
