Ken Rockwell said that
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.
Performance is great, in some ways better than the best digital cameras. Just
set it to A and shoot, not worrying about anything. No delay, no
waiting for AF, no WB setting, no battery charging, no wasting time
looking at the LCD after each shot, no viewfinder blackout, no nothing - just
great photos.
