    • Reliable Adapter with Excellent Fit and Compatibility
I purchased this lens adapter and I am satisfied with its overall performance and build quality. It fits securely between the camera and lens, creating a stable connection without looseness or installation issues. The construction feels solid and durable, and I like that it maintains a clean design that matches the camera setup well. It allows existing lenses to be used conveniently while preserving functionality, making it a practical addition for photography equipment. Overall, it is a dependable and well-built adapter that provides good compatibility and value for photographers looking to expand lens options. ... show more

    • Perfect fit for my new camera R5
Ordered new EF-EOS adapter it was opened and missing and with wrong back cap on the back instead of RF back cap it had EF probably the one who had it put the wrong cap adapter itself was fine and looked like new, returned and asked for a replacement, it came few days later that was new as it should with the correct adapter rear cap for RF and little bag for ef adapter itslef and brand new very happy with it, test it wil all my EF lenses it worked great, fast autofocus, compatible with my sigma 35 mm and 70-200 plus all EF canon lenses, its a great option so I dont need to buy other RF lenses. The only downsize i would say is that is made in Taiwan, I wish it was made in Japan since they tend to have higher quality but still under Canon so it should be ok. Make sure once you order to have all accessories since some are returns even though they advertise as new, make sure you have EF front cap with canon sign and RF back cap so it will fit when you pack, as well should have am adapter bag wraped in plaastic with canon manual and USA warranty on it, if you find all these you are good to go. Dont buy other adapters this is kind of cheap and is good quality and value using it with your EF lenses. Highly Recommended ... show more

    • Perfect fit!
I just switched to a Canon mirrorless body from my 5D Mark VI. I have several lens that have EF mounts. I bought this EF to R mount adapter and it works perfectly. Auto focus, image quality all the same. Since EF lenses are cheaper I may explore more.

    • Works great for my dental photography setup
Review Image by Coffee Connoisseur
Recently made the switch from DSLR to mirrorless (Canon R7) for dental photography. From what I saw, my existing 100mm macro EF lens was just about as good as the RF version, so I opted for this adapter and had no issues using my existing EF lens. Everything works great and was super easy to install. It did make the overall lens longer of course, but the RF 100mm macro lens would have been longer anyway, so all in all it didn't really make too much of a difference. ... show more
