This is better than other M42 adapters I've tried. Very well made and well calibrated.

Limited use so far, but good for everything I've tried and no alignment issues.

I use it for MC and MD Rokkors 28 and 100mm, secure connection, especially for the 100mm macro

Precisely milled adapter with chrome-plated bayonet mount. Nothing wobbles, neither on the camera nor on the lens side. That's why the adapter needs a firm grip and twist to lock into place properly. I can't say anything about long-term durability yet, but given the design, I'm not worried about it for the next few years. This purely mechanical version does not offer autofocus.

bought a 5€ adapter once to test the lenses. It worked fine. This works fine too, but the build quality makes it look like it's part of the camera itself. Very sturdy and good feeling. In love with it. IMPORTANT: If you are exact picky and are taking pictures of very far away objects (eg moon) and need absolute precision, this adapter (the same as any adapter on the market) doesn't focus _exactly_ until infinity. It seems to be designed with about 0.5mm more flange, and at maximum aperture (maybe for astrophotography) it falls back just a bit. Maybe removing the ring mount and sanding it a little (is 1mm thick) could help get a perfect infinity focus. Another option is to stay at f8~f11 and then tend to get decent focus at infinity (tested on focus centers 50~200mm). Quick test, focus seems to be off by 0.5mm max (I removed the 1mm ring, tested on hand and it focuses past infinity). This also seems to match the flange difference needed: Canon FD = 42mm; Sony E = 18mm; flange difference = 24mm; adapter thickness (from E base, not bayonet, to Canon FD bayonet) = seems a lot like 24.5mm. So you know. Great adapter, just grind the ring mount down a bit.

Does what it's supposed to. Feels solid. A bit tight to get the adapter onto the lens, but really no problem.
