The EOS-R does a brilliant job of correcting distortion and lateral color fringes in my old 14mm lens.
October 2018 Canon Reviews Mirrorless RF Lenses EF Lenses Flash All Reviews Introduction topSample Images Intro Versions Details Use any of these mount adapters and all Canon EF and EF-S lenses made since 1987 work flawlessly, with 100% performance with all features on all lenses, on the EOS-R system. The EOS-R defaults to correcting lens aberations automatically with most EF lenses. With EF lenses introduced since about 1992 the EOS-R has correction for distortion and falloff, and even a digital lens optimizer. You can switch any of these added features off at MENU > CAMERA page 2 > Lens aberration correction.
Versions topSample Images Intro Versions Details There are four different adapters. They differ only in features; they all do the same adapting with all of the same lenses. Each has a mount which accepts all EF and all EF-S lenses. They only have air inside; they have no optics. All are 24.00mm thick from flange to flange. The EOS-R flange focal distance (FFD) is 20.00mm and the EOS EF FFD is 44.00mm, so 44 - 20 = 24. The difference between them is that the base model Mount Adapter EF-EOS R just adapts the lens. Everything works, but it has no other features. The next model Control Ring Mount Adapter EF-EOS R adds an extra control ring. I prefer this version and it's the one shown at the top of the page. The third model Drop-in Filter Mount Adapter EF-EOS R with Drop-In Circular Polarizing Filter A adds a polarizing filter instead of the control ring, and the last Drop-in Filter Mount Adapter EF-EOS R with Drop-in Variable ND Filter A adds a variable ND filter instead.

Mount Adapter EF-EOS RMount Adapter EF-EOS R. bigger. This is the least expensive, plain adapter. $99, Canon part number 2971C002, ships October 2018. (also at B&H.)
Control Ring Mount Adapter EF-EOS RControl Ring Mount Adapter EF-EOS R. bigger. This is my favorite. It's the only one with an extra programmable control ring. Its serial number is expertly engraved on the bottom of the rear mount. $199, Canon part number 2972C002, also at B&H. Mine weighs 4.435 oz. (125.7g).
Front, Control Ring Mount Adapter EF-EOS R. bigger.
Back, Control Ring Mount Adapter EF-EOS R. bigger.
Drop-in Filter Mount Adapter EF-EOS R with Drop-In Circular Polarizing Filter ADrop-in Filter Mount Adapter EF-EOS R with Drop-In Circular Polarizing Filter A. bigger. This one has no control ring, and in its place puts a drop-in filter holder for a polarizing filter. $299, Canon part number 3442C002, also at B&H. Now you can use a polarizer with all your EF lenses, especially with ultra-ultrawides and fisheyes that have no front filter threads. Caution, it usually looks bad to use polarizers on ultrawide lenses.
Drop-in Filter Mount Adapter EF-EOS R with Drop-in Filter Variable ND filter ADrop-in Filter Mount Adapter EF-EOS R with Drop-in Filter Variable ND filter A. bigger. This one also drops the control ring, and in its place puts a mechanism to make a variable neutral density filter. Now you can use a variable ND with ultra-ultrawides and fisheyes! $399, Canon part number 3443C002, also at B&H.

Performance topSample Images Intro Versions Details How good is it? I've already tried my EF 50mm f/1.0 L and it seems to focus faster than ever on the EOS-R, and focus is always dead-on, not iffy as it always was on SLRs and DSLRs. My original EF 14mm f/2.8L not only works great, the EOS-R defaults to correcting its distortion automatically! Most EF lenses introduced since about 1992 additionally will have correction for distortion and falloff, and even a digital lens optimizer. You can switch any of these added features off at MENU > CAMERA page 2 > Lens aberration correction. Here are some of my weirder lenses with the Control Ring Mount Adapter EF-EOS R. All of them work the same:
Canon EOS-R and EF 14mm f/2.8L on Control Ring Mount Adapter EF-EOS R. bigger.
Canon EOS-R and EF 14mm f/2.8L on Control Ring Mount Adapter EF-EOS R. bigger.
Canon EOS-R and EF 50mm f/1.0 L on Control Ring Mount Adapter EF-EOS R. bigger.
Canon EOS-R and EF 50mm f/1.0 L on Control Ring Mount Adapter EF-EOS R. bigger. My 50mm f/1.0 seems to autofocus faster on my EOS-R than on any of my SLRs or DSLRs, and most importantly it always focuses perfectly, especially at f/1.0 where this lens sees as much as the human eye — something which no f/1.2 or f/0.95 lens can do.
Recommendations topSample Images Intro Versions Details The Mount Adapter EF-EOS R is all you need, but I prefer having an extra control ring so I use the Control Ring Mount Adapter EF-EOS R. Ignore either of the Drop-in Filter Mount Adapter EF-EOS R with Drop-In Circular Polarizing Filter A or Drop-in Filter Mount Adapter EF-EOS R with Drop-in Variable ND Filter A, unless you really use variable ND or polarizers, and don't have one for the front of your lens. I already use regular filters with my lenses; the reason for these is for use with very odd sized lenses for which it's easier to use a filter in the adapter rather than on the front of each lens.
