Lens Mount Adapter EF-EOS R for Canon EF/EF-S Lens to Canon EOS R RP R5 R6 R7 R10 Cameras

10/10!! This little converter works perfectly! I had 2 mirrored lenses that I missed using since getting my mirrorless camera. Highly recommend getting this one! Images are crisp, autofocus works perfectly. I am pleased! It feels durable and is easy to use. The mounting is also easy to do. It easily clicks into place. It is also light.

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.

Works perfect on my Canon R camera. Quick and easy mounting .

I was gifted a Canon R7 for Christmas last year and got this so I wouldn't need to get all new lenses, or at least give me time until I could afford a proper lens. It works great. I usually use it for my standard 18-55mm lens. I gave it a shot with my Tamron 150-600mm but I forgot my tripod and I have shaky hands so I need to give it some more time but this adapter works great.

Works fine adapting my Canon EF mount lenses to Canon R6.

Great quality, and value option is really nice. Mounts properly, but feels a little squeaky, so probably requires some breaking in. Works great overall!

works great with my canon prime lens and my Sigma 18-250 lens, but does not seem to work with my Tamron 10-24mm lens, could be the firmware needs updating on my wide angle lens or the adapter may be the issue but do not know for sure

It’s sturdy and durable! The value is extremely good as it does its job for such a cheap price. It does not affect the image quality and the autofocus seems unaffected besides speed. It fits snuggly and locks well.

Minha segunda compra, o equipamento veio errado, mas fui reembolsado. Decidi tentar novamente, e valeu a pena!

The adapter looks pretty good. I just received the package and mounted the adapter on Canon R8, it fits perfectly. I also recorded a couple of video clips and took some photographs, autofocus works perfectly fine. I would say the autofocus works better with this adapter + Canon EF 50mm 1.8 compared to Canon RF 50mm 1.8 because I do own both EF and RF 50 mm lenses. Getting this adapter instead of the canon’s own adapter sounds like a good decision because canon’s adapter is selling at a much higher price.

Funciona bien no he tenido problemas¡

tested right away yesterday on a wedding shoot and it worked as great as the OEM one but much more affordable. 2 thumbs up!!
