Canon Control Ring Mount Adapter EF-EOS R

1) Just like the basic version of the adapter, the control ring adapter works with EF-S lenses as well as with EF lenses. I use it for my Canon EF-S 10-18 ultrawide.

2) Having used a Canon film SLR for nearly four decades before going to DSLRs twenty years ago, I love being able once again to set my aperture on the lens - I'm a Manual mode shooter. This adapter adds this capability to adapted DSLR lenses.

I have both versions of the adapter. I do not really use the control ring much in my shooting. The basic version is good for me. I also got some lower cost Meiki brand basic adapters that I like a lot.

I recently found a brand-new one of these for $150 on eBay, so my two pre-RF lenses now each have their own adapter.
