This is a fully automatic exposure 35mm film camera introduced in 1968. Olympus made over 10,000,000 of them through 1988. It was, and still is, an inexpensive, lightweight camera with few adjustments.
I bought this particular sample at a thrift shop for $5 on 7/7/7 with a dented filter ring. This one's date code says it was made in 1974.
The Olympus Trip 35 operates completely without batteries. Its light meter and programmed automatic exposure system is solar powered! This makes it one of the world's most advanced cameras which provides fully automatic exposure completely without batteries or external electrical power.
The examples below are from one 24-exposure test roll of ISO 400 print film.
