The Minolta Weathermatic A is a weatherproof 110-film camera introduced in 1980. A friend of mine had one of these in hight school; I only knew it as a yellow camera. In fact it’s waterproof to 3 meters. It has a zone focus system and three different apertures all selected by the black knobs on top. The aperture knob also controls the built-in flash. A thumb lever on the bottom advances the film.
I didn’t test the integrity of the O-rings, so I didn’t want to try it out underwater. I did load a new roll of Lomography Tiger 200 color and carried it around for the better part of a week. The film leaves for the lab this afternoon.
