For photographers who already have a collection of "EF" lenses this adapter is a must have for EOS owners.
Unlike simple adapters the K&F Concept adapter comes with a range of features to make connecting your older EF lenses hassle-free, including full auto focus (with most EF lenses) and also a welcome built in image stabilising function.
The auto focus function works as expected without the lag that's sometimes present in cheaper adapters and no speed is lost.
When using the EOS onboard image tracking and subject detection the adapter performs flawlessly and as another plus point, all the EF lens EXIF information is also transferred to your image files without problem.
The adapter is thoughtfully designed with a 1/4 20 female thread on the bottom, enabling you to quickly mount it with a compatible quick release plate or attach it to a tripod.
The K&F Concept adapter has an inner matting treatment technology to reduce reflected light and minimise issues such as flare in your images and also comes complete with front and rea protective caps.
A full list of compatible cameras and lenses is available on the K&F website.

bought this along with a Canon EOS M6 and the "Nifty Fifty" with STM for the EF mount. I expected it to be poor quality or something to justify its low price compared to the Canon alternative, but it's a sturdy metal and plastic construction, easy to install, easy to remove - works exactly as advertised. The autofocus works great, the images are as sharp as can be - I mean it's a simple device, nothing really depends on it and what's asked of it - robustness and small size - it totally delivers. Unless there's something I've been missing out on these days, it's definitely not worth spending a single extra penny on something "better". Unless it can also convert without the crop factor, but those things cost €400-600, so probably not.

The functional replacement for the original Canon adapter, all my lenses fit, the M-KC-AF4 fits neatly with no binding or wobbling. Why not 6 stars? The original adapter can do one thing better: the element with which the adapter can be attached to the tripod can be removed. If you don't use a fat lens (which would require its own clamp anyway :), you can remove this element, the camera and adapter really gain in handiness. Granted, it's whining at a high level, but anyone familiar with Canon's original adapter will agree. anyway, dear friends, we are talking about a price difference of 100€, and the 5 stars are well deserved. I paid for the adapter myself and did not "invent" my review via Facebook or similar unfair practices. Who knows, maybe I'll grab the Flex, then I'll get the 6 stars *<;-)

Adapter works fine. No wobbling or jerking. Significantly cheaper than the Canon original and just as good. Buy recommendation!!

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.

Was recommended this by a photographer friend and can agree, it's the best adapter ! Not at all wobbley. Great way to get more use out of some of the excellent lenses, that can be found quite inexpensively these days, on a modern camera.
