    the adapter adds a tiny bit of length to EF lenses, but works great. I found no problems with camera communication to the lens or auto focusing.

    This will revitalize your old EF lenses. This is a must unless you are a millionaire and will buy all the RF lenes.

    My EF glass works perfectly with this adapter with the R5. Autofocus, including face detect/eye tracking, works perfect!

    A bit expensive but it lets me use EF lenses on my R6. Seems to work almost as good as using the EF lenses with a Csnon DSLR. Good build quality.

    Mirrorless Adapter to EIS Lenses

    This is exactly what I need so that I don't have to part with my collection of Canon EOS lenses. I chose this standard adapter over the more expensive ring mount with the customisable control ring, which I was not wanting. It's a little stiff attaching to the camera or being attached to by the lenses, but I think that may abate as it breaks in from being new.
