Seems well built, had very little use so far but very happy. Would highly recommend

1 star missing because it doesn’t really work well with the Takumar 50 1.4 (the lens doesn’t focus to infinity as others have mentioned). The other four stars are because otherwise it is built well and I’m sure will work with most other lenses. Using it on a Sony A7R III and it gives me nice and sharp images even with that sensor so well machined I’d say. Although I also have the same brand adapter on a Fuji XT2 and it still focussed to infinity (though it did get a little stiff at that end) so I’m not sure if they’re all manufactured exactly the same or it there is a difference from version to version. All in a all a good product.

Worked great for all my M42 lenses. Worked for even the lenses that have autofocus and need the trigger pushed by the flange to be able to adjust the aperture manually. My other M42 adapter does not have a flange to accommodate these lenses. Good build quality as well.

Excellent adapter, does exactly as it should. I can now use my selection of M42 lenses on the Sony A7ii the way they should be used.

Works perfectly! Many people are frustrated saying that the threads do not line up, or that this adapter will not work with Super Takumar lenses because of the lip. Well, it worked just fine for me!Vintage lenses are such a blast to shoot with, and this adapter is a great (minuscule) investment. The build quality is excellent, and it attaches very securely. A must-have for any Intermediate/Advanced user.Link: K&F Concept Lens Mount Adapter M42 Lens to Sony NEX E-Mount Camera for Sony Alpha NEX-7 NEX-6 NEX-5N NEX-5 NEX-C3 NEX-3

I waned this to test my old glass on a Sony FS5 camera and it worked perfectly.

The fit is not all that great with this adapter. I have a lot of K&F adapters and really expected more from them. It feels sometimes like it's not going to thread on to the lens properly. I guess you get what you pay for.
