Features
- * This adapter allows users to connect EOS EF EF-S mount lens to EOS R mount cameras. Canon STM series lenses (such as EF 50mm f/1.8 STM, EF 18-135 IS STM) don't work with our adapters.
- * As EOS lenses are electronically controlled, most EOS/EF mount lenses do not feature a manual aperture ring, so when used on our EOS-EOS R, which is a full manual operation adapter ring, the aperture could not be transferred to the camera, it will stop down to its smallest f/stop by default
- * Anodized Aluminum and Heavy Grade Brass Construction, matting varnish inside to avoid light reflection.
- * There are two types of FD mounts, the installation way and aperture control way are different, please contact our professional after sales team for help if you encounter this kind of issue.
- * Manual adapter, auto diaphragm/auto-focus is not allowed.

Infinity focus position:
• The position of the infinity mark [∞] of the telephoto lens is shifted slightly to the positive side to enable focus adjustment even when focus shift is caused due to temperature changes. The shift range is denoted by an L-shaped line, Be sure to check the focus through the viewfinder even when you shoot at infinity.
Note:
• L mount cameras are full-frame mirrorless cameras.
• Adapting APS-frame lens to full-frame camera may generate vignetting, which is not the problem of the adapter. Some cameras could correct it by adjusting to APSC.

EOS R50 + EF 18-135
Perfect fit. The lens works perfectly with the R50 body.
Autofocus, aperture priority, everything works fine.

Very high quality and fast autofocus
"First of all: the packaging is very well done. You really get the immediate impression that you're holding a sophisticated, high-quality product. It's really enjoyable to use and would make a great gift.
I couldn't find any flaws with the adapter. Everything fits perfectly. For comparison, I also used an original Canon adapter (with a focus ring). The autofocus on this K&F adapter feels a touch faster, but I can't say for sure.
The fact that the adapter also has a tripod thread, well, that wouldn't bother me too much. Cameras themselves almost always have one anyway. But it's good that if you have a heavy lens without a tripod collar, you can at least balance the weight a bit. And if you absolutely don't need it, you can unscrew the tripod collar on the adapter; the tool for this is included in the set.
So everything fits and works perfectly. The workmanship is absolutely top-notch, as are the materials and weight."

Excellent Mount
When I got my cheap mirror lens to play with my canon R6 it came with a simple
T2-EOS R mount that didn't fit the camera mount as that well. It had a slight play to it and made me worry about damaging the camera's mount.
This one, on the other hand, is quality.
It fits both the lens and the camera's R mount snuggly as any OEM lens would.
Seems very well made with a good finish relative to the cheap mount made of recycled bottle caps that came with the lens. Excellent,

Very good.
It works perfectly on my Canon R50, it even clicks when closing. I've seen several comments and I know there are cases where it doesn't work like that; it's possible it's something in the manufacturing or in the camera itself.

Fonctionnel.
Used on R3 and R5 for old Rokkor 28 and 35mm tubes. Works perfectly."

Loose ring on camera. SOLVED BY SELLER "The product does its job, it works.
In my case, the adapter has looseness in the camera mounting ring (Canon R10), and with a brief rotation, it loses the connection, and the lens becomes manual, without focus or aperture control.
I am returning it.
UPDATE
The seller has resolved the issue and replaced the product."

Very happy with my Canon R6 Mark II.
When I switched to this camera, I was left without my Canon 70-200mm f/2.8 lens (a real gem) and had to buy new gear. Until I could replace it, this adapter has been a lifesaver.

Don’t forget that it’s a manual lens adapter. Works with full manual lenses. If your lens has no physical aperture ring, you cannot control it from your camera

No Allen wrench comes with the unit and I did not need one. Mine did not require any adjustments and fit like a glove.
