Add autofocus to your manual

By Daryl

Techart I can now use my M-mount lenses and any lens that can be adapted to M-mount on my Sony and have them autofocus. This is the whole purpose of this genius adapter and it does it very well. It's small, lightweight and quiet. Older lens that you value for their special character can now be used with autofocus speeding up your creativity and helping to catch the shot.

Works surprisingly well

I couldn't believe it when I saw it, but yes, this does indeed turn your manual focus lenses into autofocus-compatible lenses on the Sony body. Don't expect perfection, but it does work extremely well. The focus motors are relatively loud, but not shockingly so. I'm now much more confident in situations where I want to use my Leica glass on my Sony bodies and have added autofocus capabilities.

Techart Pro does not list that the Techart PRO Autofocus Adapter II (Leica M to Sony E) is compatible with the Sony NEX 7. It is a very old model. And they only list "compatible with all the latest Sony Full Frame & APS-C camera models (A7R5, A7R4, A7R, A1, A9ii, A7C, A6600, ZV-E10, etc.)."
