I am coming from the 7D where I assigned image review to the set button and then used the thumb buttons to zoom into my image to check detail, focus etc. It was quick and easy and more importantly I could keep my left hand gripped to the lens.
Now this could just be that I have missed it in the manual but I can't find a way to do this on the 7D2. I have assigned the set button for image review but then I have to press the magnify button on the other side of the camera, usually with my left hand. I am using the 100-400mm mk2 and the balance is awful when doing this.
Am I missing something or can one handed zoomed image review be achieved?
