NO AUTO FOCUS! Certainly no AF on Sony A7R, A7S, NEX5n, A6300 or A6000. The listing is incorrect to specify that the adapter supplies AF on these E-Mount bodies. It does talk to the bodies with all EXIF data, Shutter Speed, Focal length and Aperture information is maintained. Accurate Aperture values are provided, a 50mm f1.8mm lens will tell the camera, at full aperture that it is f1.3. If you need this for AF on the above cameras then look elsewhere. If you use MF lenses for cinematography or otherwise, then this should suit your needs amply. Optically, this is OK. It does flare wide open. The optical lens coatings are minimum, but acceptable. There is plenty of secondary image registration when wide open. I have not seen much chromatic aberration, however, I am not using anything wider than 28mm f2.8, and on my sole Canon optic (50mm f1.8) everything looks good. On my Pentax primes, everything looks good. For $140 it is a low priced item that ultimately gets you where you want to go, if you are professional and can afford a Baveyes or Speedbooster Ultra, then I suggest you go that route (Kipon Baveyes also offers NO autofocus, but does provide superior optics and lens coatings).Read full review

This speed booster worked flawlessly in my Sony a6500 and older Sigma lenses of Canon mount. Works well with Canon native lenses as well. But remember one very important thing: you will get a lot Chromatic aberration with this adapter - speed booster especially with wide lenses. You will have to correct Chromatic aberration in post processing. Sony bodies do not support automatic Chromatic aberration removal of the speed boosters. I hope that my recommendations will help you!
