Canon EF-EOS R Mount Adapter

Canon's official EF-EOS R mount adapter, converts a Canon EF lens to mount on a Canon RF-mount body (R5, R5C, R3, R8). Full electronic communication: AF, IS, aperture, EXIF, with no performance penalty versus a native RF lens. Solid metal construction; this is the basic, no-control-ring version. We use it whenever a Canon EF lens needs to live on an RF body, most often when our Canon CN-E primes or a Canon EF L zoom is the right glass for an R5C build. Worth knowing: there are four variants of this adapter (basic, control ring, drop-in filter, drop-in variable ND). We have the basic.
