EOS 7D Mark II: Quick card check

The EOS 7D Mark II gives you several options of what information to show through the viewfinder. One of these is for image recording quality. This is a good one to set as it offers a very quick check to whether there is a card in the camera or not. If you don’t see this through the viewfinder, then you don’t have a card installed in the camera. With no card installed, the recording quality will not be shown.
