My stepfather gave me a Nikkor f1.2 50mm! To adapt it to my Canon 70D I had to get a ring... it's really nickel, I don't regret the purchase! No games and no snagging — it's easy to put on and take off! I recommend buying this item with your eyes closed.

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)...!

Ring to adapt Canon FD lenses to EOS R-mount bodies with no electronic contact so no autofocus You have to use the case manually to adjust it. ISO and speed, the aperture is set on the lens

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

treated myself to this adapter to adapt old lenses with the Canon FD bayonet to my mirrorless Canon RP. This works absolutely perfectly. The adapter sits on the EOS-R bayonet without any play and the FD lenses fit snugly on the adapter. Focusing to infinity is possible. That doesn't seem to be the case with all adapters. With the corresponding K&F adapters, I have already had good experiences with my Olympus OMD EM 1.2. It is important that the locking ring on the adapter is first turned in the "OPEN" direction. Then the FD lens with the smallest f-number, eg 1.8 or 1.4, is attached, then the lock is turned to "LOCK". The desired aperture can then be selected manually on the lens. The locking ring on the FD-EOS R adapter is much tighter than on the MFT variant; there he can easily adjust himself in the direction of "OPEN". That's where you learned. Therefore, this adapter receives my unreserved recommendation. I will gradually buy more K&F adapters (e.g. M42) for the RP, simply because I have not been disappointed by the price/performance ratio so far.

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.

bought this adapter ring because I couldn't sell a Tamron EF after selling my Canon C100 mkII and wanted to try it on the Fuji X-T4 without spending too much on an adapter with electronic contacts. I couldn't find anything better for the same price. Very high-quality workmanship, very stable and solid. Recommended!

Great adapter ring. Purchased to adapt CANON EF series lenses to Fuji XS-10 camera. They work great. Warning to potential buyers. To use the adapter, you must set the camera to "Shoot without lens" in the menu, otherwise the shutter will not activate
