Minolta's 1980 waterproof 110 camera — yellow, Rokkor 26mm f/3.5, usable to 5m depth.
The Weathermatic A was Minolta's watertight pocket camera for 110 cartridge film, launched in 1980 as scuba diving and watersports boomed. Its bright yellow shell and oversized controls were designed for use by gloved divers, and it preceded the 35mm Weathermatic 35DL and Weathermatic Dual 35 that Minolta sold later in the decade.
It carries a Rokkor 26mm f/3.5 lens of four coated glass elements in three groups, zone focusing across five selectable distances, and a fixed 1/200 metal-blade shutter with three weather-symbol aperture settings. The bright-frame finder includes parallax marks, focusing symbols and a CdS-driven low-light indicator, a flash is built in, and a single AA cell powers the electronics. The sealed body is rated for underwater use down to about 5 metres.
It suits collectors of underwater and adventure gear and anyone shooting 110 film at the beach, pool or on a boat; the fixed shutter and symbol apertures keep operation dead simple, and the yellow body stays visible in the water.
110 film remains available new from niche producers, so the Weathermatic A can still be shot. Inspect the sealing gaskets before any wet use — forty-year-old rubber may no longer be watertight — and check the flash fires and the battery compartment is corrosion-free. Many examples carry dive-kit scuffs, so clean, well-sealed ones command a premium.
