The Pentax PC-313 is a lightweight and simple autofocus 35mm film camera with a 35mm f/4.5 lens (3 elements in 3 groups). It requires 2 AA batteries (not included).
Condition notes All functions of the camera were tested with a battery installed and film running. The film was not developed. With the exception of the silkscreen that says "Pentax PC-313" being worn off (very common in this model due to the ink type used), the camera is in very good aesthetic condition (see photos).
