I have a Samsung NX 500 and the adapter fits perfectly, I've tried it with a Canon EF lens and it's perfect. It only works in manual mode

This adapter fits my Nikon J1 perfectly. I can use my Canon EF 75mm-300mm lens.

Works like a charm on my Nikon 1 S1 camera and allows me to use my Canon EF lenses! Solid construction!

I use this adapter on my Canon M50 Mark II and am satisfied. The old EF-L/S lenses can be used with it. That makes you want to keep using the old old lenses. The autofocus works without problems. Only the adapter is mostly made of plastic, but this has not affected the functionality so far.

Yes... it works perfectly with Canon EOS M cameras. I own Canon EOS M10 and use this adapter most of the time with Canon 50mm 1.8 lens. It is amazing. The autofocus is accurate and fast enough. If you own a Canon EOS M camera, I recommend you this adapter because it is much cheaper than Canon original and there is actually no difference between them. Everything works as it should. I love this adaptor. The best purchase I've made for my camera.

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.

The lens adapter is used by me to use high quality Nikon lenses on a Canon EOS M camera. The adapter is of high quality, the handy metal ring allows manual adjustment of the aperture. Note: electronic transmission of the lens data or the autofocus is not possible with this adapter!

Since I recently inherited a Nikon FG-20 as well as a Nikon Micro-Nikkor 55mm f/2.8 and a Nikon Series E manual focus zoom 70-210mmf/4.0s, I naturally wanted to use the old lenses on my Canon EOS 600D or EOS 600D Review Canon EOS 760D. But: Nikon on Canon? It is well known that this is not possible without an adapter ring. Novoflex adapters were out of the question for me, because as a hobby photographer and occasional "analogue photographer", I didn't want to spend €100 on such a ring. Nevertheless, I wanted to break THE primal law of photography and combine Nikon and Canon. K&F Concept offered a cheap alternative for just under €20. The adapter ring is surprisingly high-quality and made of metal, and it can also be quickly mounted on the lens and DSLR. I was surprised by the results (see photos) and would not have thought that the two 30-year-olds "harmonize" so wonderfully with my EOS, to put it bluntly. It's a bit "hooky" to detach the adapter ring from the lens again using a tiny little "hook" (if you can call it that...), so the ring gets a star deduction, because it gave me a bit of a panic at first and I'm not sure how long this "hook" will go along with the whole procedure. ! A NOTICE ! You should really inform yourself in detail about the bayonet (connection of the lens) beforehand. Since the two Nikon lenses are both a bit older and were built in a time when people would have laughed about something like the internet in this country, it was a bit difficult to find out exactly (especially as a layman or newcomer to Nikon and analogue photography) whether they both have the same connection and whether I might even have to buy two different rings.
