Hello all! I just got my hand on a Mamiya press 23 yesterday. The view finder is extremely blurry and I havent found a way to clean it thoroughly. Despite all that, i still shot a roll but the film came out all out of focus. The lens is 100 mm retractable 3.5. The bellow is broken so i did not extend it. Is it necessary to extend the bellow to shoot or not? or the out of focus is because of something else?
