For M42 to EF mount

O stars. Faulty product. Please do not buy and waste your money.

I looked at several of these adapters and narrowed it down to this or the k&f. Since this was cheaper and the reviews were good, I figured I'd give this a try first. It works great on my canon DSLR and my canon m50 with the EF to EOS M adapter I already had. It's got some weight to it and feels solid. I was able to thread my lens smoothly and was able to mount and unmount it from the cameras without issue. I don't notice the click like you get with Canon lenses, but I can't unmount it without pressing the release button. I like it best on the m50 because it has manual focus peaking, which makes it really easy to nail the focus. Also, I had no issues focusing to infinity on either camera. Great product overall. My only wish is that it would be black to blend in with the camera better, but it's not worth the extra money for the black k&f, imo.

sigue funcionando, es una pieza de maquinado solida, no me ha dado lata ni causado problemas, hace lo que promete

Good
