Back around 1980 I decided to get a 110 camera to carry fishing and hunting that I would not have to worry about. I chose the Minolta Weathermatic A watertight pocket camera. The bright yellow, easy to find, color and the large, glove friendly, controls were very helpful.
The lens is a Rokkor 1:3.5/26mm f/3.5 zone-focusing (4 coated glass elements in three groups) beauty, focusing from 3 feet to infinity, using a continuous-control knob. There was even a table engraved on the bottom showing the distance for each symbol.
The shutter is mechanical with a single speed of 1/200. 3 apertures are selectable with a knob, one for sun, one for clouds or one for flash. The viewfinder had a bright frame finder with parallax correction marks, low light indicator and focusing symbols.
The flash and Cds (light meter), powered by a single AA battery, is built-in and selectable with an aperture switch. The film advances by a large lever on the bottom. The wrist strap has the actual flash range for ASA 100 and ASA 400 film.
I never tested the maximum diving depth of 16 feet but it was floating around in the bottom of the boat a few times. In camera shops they would have a sample in a fish bowl for a display unit. This one was hollow and weighted to stay on the bottom. The actual camera floats.
It was the first waterproof 110 camera and did a great job. I was always pleased with my photos. I used it until about 1987 when I upgraded to the Minolta Weathermatic Dual 35 Camera (35mm).
