    Basic Mount Adaptor that works

    I use this mount adapter to mount my EF lenses to my Canon R5 camera. My lenses are mostly by Sigma. I have not had any problems in its use. I have seen people on some camera forums state they had problems with other brands of adaptors. My feeling is the cost of the adaptor is small fraction of the price of the R5 or even a lens, why buy an off brand that might not work?

    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.

    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.

    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.
