Holds up my Canon EOS M50 just fine. I also like that it came with an adapter. When I tried to screw the ball head on my tripod, it was too big. I was frustrated as I really needed to use the ball head and I was thinking I had to return it. But then I found the adapter in the package, screwed it into the ball head, then attached to my tripod. Easy peasy.

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.

With this adapter I can use my old MINOLTA lenses on the Canon EOS R. Works well. The connections run smoothly and the lenses are tight. But you have to be aware that the aperture and distance on the lens have to be set manually. "Release without lens" must be activated on the EOS R (menu 5/5). Otherwise the camera will not trigger. Set to Av aperture priority.

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.

I can only recommend the adapter. I ordered the adapter to be able to use the lenses of my Canon A1 on my Canon EOS 400 D as well. Everything fits without any problems, nothing wobbles or jams, even though the lenses on my A1 are from different manufacturers

I bought the M42 lens to use with Canon EOS.
I could use it without any problems!
