Hmm, not quite my experience based on my use of the M cameras, which use the same DPAF system. It’s possible that part of it has to do with the really large focus box, though. I’d like to see it in practice. In fact I thought I even heard one of the (p)reviewers say that they found the R had occasional issues focusing at 1.2...There will be substantial value in the fact that the RF version will actually hit perfect focus nearly 100% of the time. The sharpness of the EF 24-105 doesn't mean much when back or front-focused.
