bought the adapter to use my Canon EF 50 1.8 STM and my Canon EF 35 2.0 IS USM on my EOS M. The adapter fits perfectly on my EOS M. The lenses are almost too tight compared to the direct ones themselves, which suggests comparatively high manufacturing tolerances and is consistent with some other reports (hence only four out of five possible stars). Both lenses are fully functional and the autofocus also works perfectly. For example, I can't determine (without having measured this) that the EF lenses with the adapter focus more slowly on my EOS M than the original EFM lenses. I also find the low weight of the adapter very pleasant, so that at least my two EF lenses are not too top-heavy on the EOS M. Addendum on 04/26/2016: In the meantime I have to revise my first impression, because the adapter only seems to have been a little too tight at first. So I'm upgrading my rating by one star to 5 stars.

brief history of why I am writing here: my wife is a professional photographer (those who are interested can find Uschi at engelmann-fotografie.de) I myself am a stage manager and look after around 700 events in all quality classes every year. Photo logging is often desired, but there is usually no budget for a fully paid service provider at the start. I made a virtue out of necessity: I bought the Canon M50 and with the adapter I have access to all my wife's fat lenses. IA I'm on the road with a small bag and my equipment, do the job on the side and despite "little time and little knowledge" I have a great arsenal of PICs available, which are also paid for.

Specifically to the adapter: the lock fits on both sides, all tested lenses work properly. no gaps or other problems. However, this refers to a 2-day test period, if anything changes, I will upgrade :-)

Great product I bought it for my Canon EOS M 50 mark 2 and found that it also fits my Nikon d 3500 SLR.

In no way inferior to the Canon original. The only annoying thing is the non-removable mount at the bottom, which is made for mounting on tripods. It feels a bit weird at first, but I personally got used to it over time. The processing quality is good and robust, I've had 2 of them for almost 2 years and they are still in perfect condition. Costs far less than Canon's original and makes only minimal compromises! Excellent!

Very useful for using my old Nikon manual targets (no autofocus) on my Canon EOS RP. Great results, no appreciable bias for missed alignments. Bayonet insertion with the right tolerance, neither too tightened nor too much leasure. You get great performance with manual focus.

All good, the quality seems good, it fits the body well and the lens attaches neatly. Infinity focus is supported (not at the infinity mark, but that's probably because of the lens).

It goes perfectly with my old Yashica lenses for the Canos EOS RP. The lenses work in full manual mode (iris and focus) and the camera can take snapshots as long as we program it to be able to shoot "without a target" in the dedicated menu. Actually, I had already bought an adapter with the same function for a Canon EOS M5, so I had experience.

Great adapter in its price range. I don't notice any particular flaws, the tolerances look very good. Finally, K&F decided to paint the interior with anti-reflective paint.
