have a few of these K&F adapters for mounting various vintage lenses on my cameras - I use Canon and Fuji ASP-C and M4/3 cameras and they are brilliant on all 3. Great price, well made and they work really well.

I have an old Canon 550D and some Lens. And now I've bought a Canon eos m100. I want to keep using my EF Lens. Then I buy adapters. This works perfectly and can autofocus very quickly.

Works perfectly, Canon fd 50mm f1.8 and Vivitar Series 1 70-210 f3.5 come alive again on the mirrorless Canon M5. Really happy with it!!!

bought three adapters with a Canon R mount (one for Leica R, one for Contax and one for Minolta MD). They all reach exactly infinity. The internal anti-reflective paint is well finished. When I check them with a caliber, the two sides of the adapters appear planar (but I don't have any wide-aperture lenses to test that on). On the camera side, they are all precise and without light leakage. On the optical side, I noticed a slight light infiltration on two adapters. Of course, I purposely searched for them by bringing a 500 lux LED flashlight half a centimeter away from the adapter. Light penetration is very unlikely in normal situations (perhaps on an easel on the beach in August). I solved it anyway with a small rubber grommet. If you're shooting freehand, that's not necessary, the hand is hiding a possible infiltration. Overall they look like good adapters to me. Due to their robustness, they can withstand lenses up to 600/700 grams. However, I would not mount lenses that are larger than one kg on the nose.

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.

bought the EF50mm primarily for street photography and am extremely satisfied with the performance in this area. Amazingly, this lens is actually sharper than the 50mm from the Canon L-series at an aperture of 5.6. The aperture of 1.4 and the associated light sensitivity is very pleasant. However, with an aperture of 1.4 you have to deal with a decent decrease in sharpness and - especially for indoor shots - with clear chromatic deviations. The bokeh is very nice and soft. Something special. The autofocus is fast, accurate and also quiet! The weight of 350 grams makes this lens a welcome lightweight in the bag and on the body. The price is unbeatable. You get a really good lens for everyday use for your money. Conclusion: Compared to the much more expensive 50mm from the Canon L series, I would always use this variant. My purchase recommendation for street and snapshots etc. if you don't absolutely need a red ring!

The adapter is ONLY for manual lenses from Canon's FD series. Find the adapter super and this is in top quality.

Great filter I didn't find a color cast used on Canon L-series lenses, no problems, the only thing I found is that the rings are a bit tight but will probably wear off over time.
