Canon EF-EOS R EF/EF-S Compatible Mount Adapter for Canon EOS R

I have been using the mount to convert my EF 75-300mm lens for my R50 body, and it's been a seamless transition. Can't recommend enough!!! Worth the money.

Works as advertised. It does the job. I had no trouble using this product

I am pleased to have purchased this adapter for it provided the opportunity of utilizing the many EOS L lenses purchased.

I love the new R6 Mark II and the adaptor allows me to use the Canon lenses that I have invested in over the years for my other Canon EOS cameras...

Decent price for just the adapter, love the versatility it adds to EOS R camera line, being able to use the high-quality EF lens I have on this camera is absolutely amazing!

Works perfectly, I just wish it wasnt so long but I understand they had a reason.

Well made. Great interface between the EOS lenses and R Bodies. I have one on my R and my R5.

Refurbished product but works great. Item is in great shape

A mount adapter that permits long-tern Canon camera users to use those EF lens's, some that are excellent and quite expensive, with your new R5 camera body. A simple job to do, and it seems to work OK with my EF lens, but my nice Tamron ultra-wide angle lens is not usable due to strong vignetting.

I was gifted an R7 to replace my 77D. I don't have the funds currently to buy new lenses so I bought the adapter so that I could use what I have. I haven't used it much, shot some wildlife photos while on vacation. It worked fine for that.
