The Vivitar PS:35 Auto Focus DX is a nice 35mm point and shoot camera from 1980s. This camera will only fire the flash if you switch it on (always a favorite feature of ours); there is a low light warning LED.
The camera requires two AA batteries (not included). We unfortunately couldn't locate a manual but the camera is very easy to use.
Condition note We tested all the camera's features with film installed and it's working correctly. The camera is very good cosmetic condition as well (see photos).
