Hi, I was actually meaning IQ and focusing type things with the distance between the sensor and the lens.

As I said: no problems -- regarding AF performance and IQ, both of which also depend on the camera body's sensor, AF subsystem, and processor.

I have experienced no AF degradation using Canon EF lenses on my 80D, 5D Mark III and 6D Mark II versus using them with a Canon RF-EF adapter on my R. (A mirrorless body removes an inherent DSLR challenge: AFMA.) IQ, in particular, is always better coming out of the R.
