Magnesium alloy covers with weather sealing over a magnesium alloy chassis. The control layout is basically a new arrangement with a much greater reliance on customisable multi-function controls and only a few similarities with the higher-end D-SLR control layouts. As on the Nikon Z cameras, the top deck info screen is an OLED-type panel. However, the handgrip is deliberately more D-SLR-like in size and function. Curiously though, there’s no joystick-type controller for faster AF point selection, but this can be done from the touchscreen. Completely new – and pretty neat too – is a multi-function touch-bar (the ‘M-Fn Bar’), located alongside the EVF eyepiece, which is swiped either left-to-right (or vice-versa) to make setting adjustments for one of 40 assignable operations (including white balance settings, sensitivity, shutter speeds, etc.). Of course, the good news is that the EOS R is markedly more compact and lighter than the EOS 5D Mark IV and EOS 6D Mark II or even the ‘APS-C’ format EOS 7D Mark II. Body-only weight is 580 grams versus 800 grams for the 5D IV. That said, Canon is emphasising the possibilities with future lens designs that the mirrorless configuration will allow rather than simply just a smaller and lighter camera body.
