The Vivitar PS20 is a simple 35mm point-and-shoot from the 1980s. It features an autofocus 35mm f5.6 lens and DX coding for automatically setting film speed (between ISO 100 and 400). The camera will allow you to take photos either with or without flash.
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 The camera is in good cosmetic and functional condition.
