The Olympus Trip 35 is a classic scale-focusing, autoexposure 35mm camera that needs no batteries. That's right: zero batteries. Quick and easy to use: just set focus and hit the button. If there's enough light, the camera will take a picture; if not, it'll lock the shutter. In excellent condition, with a clean 40mm f2.8 D.Zuiko lens and new light seals.
