Lens Mount Adapter Compatible for Leica M Lens to Alpha Nex E-Mount Camera Body with Matting Varnish Design

It works perfectly well.

quite solid built, a bit too tight. Still work perfectly. Being tooTight is much better than too loose.

The K&F pro adapters are definitely top notch adapters. I’ve bought these adapters before for different camera/lens combinations and they are night and day better than cheaper alternatives. There’s no wiggling and it’s a clean mount.

It would be a great adapter if it wasn’t for the fact that there is a light leak. Not terrible but it just shouldn’t happen. Maybe a defect.

I can only speak for the version that I purchased which is the Leica M mount to the Sony E mount. I have about 10 different lens adapter types and this one has better fit and finish than most. It does cost just a bit more but the quality is better.Been taking pictures today with a Leica M rangefinder coupled lens on a Sony A7 camera with great results.The E mount side went on smoothly with minimal play, no light leaks and not too loose nor to tight. Not as good as a factory lens mount, but I have no concerns on the fit. About average or better compared to other adapters.The Leica M mount side fits great, as if it were a factory mount.It's better than I expected and I would purchase this version again.Hope this helps.
