    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.

    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?
