I've had Canon cameras for over 40 years and for the last five of those I've used an EOS 5D MkIII. I'm very much out of the loop these days re current developments in camera technology, the reason being that I'm very happy and settled with my own kit and, in retirement, I'm fairly unlikely to keep upgrading my kit. However, nobody can have failed to have at least heard the term 'mirrorless' even if, like me, they've not felt curious enough to find out about it. My understanding is that there will no longer be a prism, because there will no longer be a mirror to reflect the image up into the eye piece. Will it then be the case that, even with pro cameras such as the recently announced EOS R, we will have to learn to take photographs with the camera held at arm's length (in the manner of a smart phone) to view and frame our shots, using the little screen on the back of the camera body? If that's to be the case then count me out, as I cannot imagine not holding the camera to my eye to take a photograph. OK, so I appreciate that I have to use the 'smart phone' technique for video, but frankly I don't like it and it's mainly for that reason that I rarely bother to capture video images.
