Well I wanted to learn to use my Yashica MG-1 since it used 35mm film. Except there was one question that everybody asked: do you need the battery. I found the answer to be yes and no. You need the battery to have all of the exposure times and the flash, however you don't need the battery if you don't mind shooting in 1/500. I won't mind it. Also expect to see an album once I get some rolls of film processed.
