Works perfect.Build quality is 10/10Used with:Sony A7iiMinolta MC rokkor x 50mm f1.4Mounts perfectly, no issues with fitment. Snug but not too tight. Would definitely purchase again if i need to adapt other vintage lenses. Keep in mind there is NO communication between lens and body. It just allows you to mount it. This means everything is manual focus.

This is K&F Concepts 2nd version of their MD to NEX mount. This one currently doesn't have as many reviews, but is superior to the first - I've owned both.Quality and compatibility are a given at this point - K&F nailed this on the first version. The design improvements made to this version include the chromed camera mounting bayonet, the application of anti-reflective coating on the inside, and adding an ever so slightly amount of thickness to the top of the adapter.As a result - the camera mounting mechanism is a little sturdier, light won't reflect off the inside of the adapter and add aberrations to photos (rare case), and there is slightly less beyond infinite focus which gives you a tiny bit of additional minimum focus distance. The ability to focus beyond infinity was never a strength of the first version, and while improved on this version, could still be better.The only negative I can think of is these are currently only shipping out of China. Maybe that will change in the future.Get this version over the other one. It's better.

Quality is good. Not sure if this is case for all adapters, but it focuses 'beyond' infinity. In other words, when you want to focus to infinity, you can't crank the lens all the way to infinity focus as it will be blurry. Rather, you have to focus for slightly closer than infinity for image to be sharp. A bit of an inconvenience if you're trying to focus quickly.Another thing that would be nice would be a mechanism to open the aperature blades quickly for focusing (rather than using aperature control on lens). This would allow you to focus with lens wide open (useful in low light) and then take the photo without having to look at lens to set desired aperature. Again, this would be a convenience.
