Canon EF to RF Adaptor

This Canon adapter works perfectly and is well made. I'm keeping a few big white EF lenses and using the adapter rather than having to replace these expensive long lenses.

Bought this when I upgraded form a Canon 80D to the R5. Works just fine with my Canon and my Sigma Lenses. I use a Canon 18-135, a Sigm 18-35 Art, and a Sigma 100-400 Contemporary. All work just as they did on the 80D.
