so i just got an Olympus OM-1 and i normally us a cannon rebel t3i so ive never used a film camera before and im trying to figure out what some things are and what they do. So i know that the batteries for these cameras are hard to find and can be pretty expensive and i also know that the light meter uses the battery but idk what the light meter does or what its used for. I'm not sure what the mirror lock-up does or when i should use it. if any of yall could give me some tips or advice I'd really appreciate it.
