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

Everything worked great at first, but problems soon arose. I have to contact the manufacturer because now almost every time I use it I get problems with the aperture control or shutter control or whatever and have to restart the camera until it decides to work. I already knew that autofocus would be practically useless. Since most of these adapters don't have good autofocus speed, even the Metabones won't work and is 4 times more expensive. Although I work with a camera and don't need autofocus to work well, I didn't expect to have trouble with anything else. PS If you are a photographer who needs auto focus, run away from this product. This will be a waste of time.
