Actually I like Canon R, it does not shine spec-wise but it’s a solid workhorse. I agree that Canon should drop EOS-M mount (a wasteful distraction) and focus on RF mount in APS-C and full frame implementations with a range of affordable budget lenses.
Would I buy Canon R today? The answer is no. Canon R falls short in megapixel count against high resolution models of Sony, Nikon, L-mount alliance while being in the same price range. I’d like to have an option of using EF-S lens on RF-mount body with adapter and still getting at least 24-26 MP resolution. Sony ‘s approach of one mount fitting both APS-c and FF lenses is the winner.
