I recently bought a Canon AT-1. It's in great shape except that the aperture needle in the match needle system has been dislodged at some point and is floating around inside the viewfinder. The light meter needle still works though. I was wondering what the best way to get great exposure is without the aperture needle. Do I just aim to have the light meter in the middle somewhere? Do I use the stop down button? I can't afford to get a separate light meter at the moment. Any suggestions would be great.
