  • Works fine and much lower cost
This works perfectly to enable using my Canon and Sigma EF mount series lenses on my new Canon R50 V camera with the new R mount. This product is less than 1/4 the price of the Canon branded version (model EF-EOS R) when buying from Amazon and is solid and allows full function identical to the Canon product. It adds hardly any weight or length to the camera plus lens and has no batteries or moving parts to wear out. Full Autofocus and Image Stabilization functionality is retained. ... show more

  • Works perfectly
Fits perfectly. I have a canon R6 and EOS 50mm f1.2 this mount is snug and works well!

  • Works as it should
Works exactly as it should. Solid, compatible with RF/EF bodies and lenses, and overall a great deal. There is no loss or degradation in image quality.

  • Works well
It works good on my R7 to attach an older 24mm E lens fit on camera smooth and easy but lens seamed a little ruff and tight. But at a third the cost of the name brand it’s not bad.

  • Great adapter
This is a great adapter for using your old DSLR lenses with a new R canon camera. Easy to use and works great.

  • A great alternative at a great price
The YKEASU ef to ef lens adapter is an absolute work horse for the price you pay, it fits perfectly on the RF body with only slight resistance towards the locked in position for lenses. It seamlessly identifies my EF 18-135mm lens and focuses and zooms in and out perfectly, while I haven’t tried it in any intense situations to test its weather sealed abilities I will update when I do try it out. There’s not play in the adapter which I know is a common complaint when it comes to other ef to RF adapters but this stays perfectly in place with no play. The only complaint i have which isn’t a major one is the lack of a thread adapter or some kind of mount to allow a tripod to thread into the bottom like other adapters do, but honestly it’s not a huge thing since I mainly shoot by hand but it would be nice to see them implement that into another version if they decide to do one. But I’m all honesty This adapter is a great alternative to the canon one and makes it an essential item in photographers tool kits. ... show more

  • this adapter works just fine
This was a tight fit at first but has loosened up over time with some use.

  • Just so it
Just as good as the name brand but more affordable. I have 2 of these, for my R8 and R6 and I bolt on all of my ef glass on the rf mount.
