Firstly, I have over 100 vintage lenses, so I've tried so many different adapters and this was the first K&F adapter that I bought in 2015 (I'm going through my old purchases to leave long-term reviews). Since then I've bought quite a few more K&F adapters for my other mount lenses, so at this point, you might be able to guess that I like these adapters a lot!So why do I like them so much? They are not the cheapest adapters out there, but for the price, they are the best adapters I've tried so far. They fit onto the camera quite snuggly which is obviously a good thing and the same can be said for the lens side on the adapter. Overall build quality is very good, even better than I would expect at this price point, so I highly recommend these to anyone using vitnage lenses on modern cameras!

Excellent adapter, works brilliantly on my A7 with a 50mm Yashica. Have used this for a lot of paid work so continue to trust it completely. Robust.

The adapter works well on my Sony A7ii. The fit is spot on and it let’s me use some great affordable zeiss glass. Would highly recomend this as a cheaper alternative to the metabones version.

I have several K&F Concept lens adapters to put my legacy lenses on today's digital cameras. These adapters are excellent, well made, nicely finished, and work perfectly.

Using this adapter on a Sony A7Rii with a Contax 50mm f/1.4 Planar lens. The fit to the camera and to the lens is perfect. Not too tight, and not at all loose. Perfect.
