All my EF and EF-S lenses work with this adapter on the EOS M. I had previously bought a cheaper adapter without electronics, which I use to adapt the small camera to a telescope. But the electronics are very practical for everyday use with photo lenses! I don't know the Canon original, but there's nothing wrong with this variant. Clear purchase recommendation!

everything fits me without play, even the tripod thread (Manfrotto plate) - at least here there is nothing against the replica and 70 euros more in your pocket ;) (by the way, Canon has a cashback campaign until the end of January 2017 - give me 75 credit for the next purchase (that 22mm lens) and 35 cashback on the lens ... so I get the part for 105 euros;)

High expectations for this lens not needed but it allowed me to use the old lens and I tested it which worked beautifully. It will cause some difficulties for me to use it for the first time, but look it up online to see how it works. I did it and it worked fine.

Automatic extension ring for Canon EF | EF-S lenses on Canon M bayonet. Fits perfectly and the price is just great. So there is no reason for Canon users not to get a smaller M-series camera and use the extension ring for the existing lens park. LG, Mizerovsky

Bought the wrong adapter. The quality of the adapter is very good, a well built device, I got the right one and I am very happy that the adapter fits well and I can now put an old vintage lens on my new tech camera. Overall happy with my services which is why I gave 5 stars. The company easily refunded me upon my return.

Fits wobbly and has air in the truest sense of the word. In itself a very good product, unfortunately the bayonet in the axis of rotation has a little play between the detent and the end stop. As a result, the adapter rotates a little when it reaches the end point when zooming. The only question is whether it's the same with the original... Unfortunately, I can't compare it. Otherwise TOP !!!

Seams reasonably sturdy. Works with old and new(er) FD lenses. The ring that moves the DoF preview lever does not have a positive detent.

needed an adapter to adapt EF/EF-S lenses to my Canon EOS M50 and I am enthusiastic about this K&F Concept adapter, the part is cheap and fulfills its purpose 100%, I also think the possibility of connecting the camera and lens directly to the Being able to attach the adapter to the tripod means that the weight of larger lenses does not weigh directly on the camera.

Have (as I'm sure most) no comparison to the Canon original adapter, which costs about 2-3x as much. The adapter works as expected for me in connection with a CANON EOS M100 and a Canon EF-S 55-250mm, I don't know what the original should be able to do better. Autofocus seems slower than with the EF-M standard 15-45 kit lens, but is sufficient for my needs. Covered the range from 15-250 inexpensively. Can't imagine that I noticeably miss the missing range between 45-55. Snaps in perfectly on both sides, sits firmly without misaligning in any way. It seems to me that it is built a little unnecessarily too deep, but I don't know whether the distance has to be like that for optical-physical reasons?

Works well on my Canon M6 Mark II mirrorless. Would have given 5 stars except the mounting lock doesn't engage so it's too easy to twist slightly. When rotated, the lens opening is prevented from narrowing to the set aperture.
