The Canon EOS R has now been in the hands of a select few, and following on from the early impressions and all of the noise about card slots, Tony Northrup has pitted it against the camera that Canon is seeking to challenge: the Sony a7 III.
As you'd expect from Northrup, this is a no-nonsense runthrough of all of the major features of each camera and how they stack up against each other: focusing, frame rate, video, controls, autofocus, dynamic range, and the selection of lenses. There are clear benefits to each, though it's possible that, for the most part, one edges it over the other. For some, the flip-out screen of the EOS R will be decisive, but for serious videographers, this will never be enough to justify many of its shortcomings, such as the 4K crop factor.
Something that I've only just discovered is that, like the Sony, the Canon will charge its battery in-camera via USB, but only if you are using the native Canon charger, the PD-E1 USB Power Adapter, which, when it hits the shelves in February next year, will cost an astonishing $190.
A hat-tip to Northrup for somehow managing to keep a straight face when doing the video autofocus tests. Brace yourself around the 11-minute mark, and consider yourself warned if you suffer from pupaphobia (fear of puppets).
