    Adapts you’re EF lenses to the new RF mount (EOS R) works great. EF lenses focus the same as they would on any other EF mounted camera.

    I got this adapter as an early Christmas gift for my husband. He loves it. It makes his Canon lenses from his old Canon camera work with his new Canon EOS R6 Mark II camera. Perfect match up. Would definitely recommend.

    handy little item.... but my HONEST advice..... if you are gonna spend 4 grand on a new mirrorless camera.... go ahead and buy the RF lenses to go with the camera.... lesson learned!

    I'd personally go with the command ring version since I've got the EOS R and missing that 3rd dial can be a bit annoying.
