I have just started testing my A7r in the field and I am finding a most annoying behavior that I hope there is a workaround for. When I zoom in on an image to check for sharpness and try to examine with a loupe, the LCD goes black. I know this is set at auto in my settings but my only option seems to be auto or leave one or the other on. Is there a workaround to be able to leave the LCD on? How else would I be able to check for critical focus?
