Olympus Trip 35 lens mount_Olympus OM but when you absolutely positivelyThe 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. Light cosmetic wear, with a few spots of discolouration on the rear body covering.
