Yes, it's adjustable, but with some EF Canon lenses it's impossible to take stock.

Yes, it fits perfectly on my Samsung Nx 3000 mirrorless camera and Canon lenses have no problem even if there are no more automatisms.

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.

already had rings to use Canon FD lenses on my Mirrorless Samsung NX30 but I wasn't entirely happy with them... on a friend's suggestion I wanted to try them and I have to say that from a constructive point of view they are really well done . No mechanical play, the lens is firmly attached to both the ring and the camera body and not even the stop-down ring of the apertures (which allows you to set the aperture to the desired value) remains locked in the selected position. We recommend!!! Top shipping service (as always)...!

That's the nice thing about modern mirrorless system cameras: You can continue to use older lenses that were intended for analogue SLRs by connecting them to the camera using a manual adapter. This works very well, you even have a preselection aperture facility, ie you only set the aperture on the lens, only when you take the picture do you turn the aperture locking ring on the adapter to the position - very helpful. I can only recommend using "old" analog lenses on the new mirrorless ones! I bought a Canon FD 50mm macro, an FD 100mm macro, an FD 35-70 and an FD 80-200 for a few euros and I am extremely satisfied with the image quality on the 61 MP sensor of my Sigma FP L, even with 100% view on the monitor. The lenses mentioned are sharp to the edge. This turns out to be a myth that analog lenses cannot be used digitally because the resolution of these lenses is too low. I can definitely recommend the K&F adapter. It is precisely manufactured and slides smoothly into the camera's bayonet.

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.

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.
