The Minolta Weathermatic 35DL, launched in 1987, is the instantly recognisable bright-yellow submersible 35mm compact — a proper waterproof camera rated to 5 metres depth, descended from Minolta's earlier Weathermatic 110.
It shoots full-frame 35mm through a switchable dual lens offering 35mm and 50mm focal lengths ('DL' = dual lens), with autofocus, a built-in flash, DX film-speed reading, motorised advance and rewind, oversized gloved-hand controls, a sports-finder option and a chunky sealed polycarbonate shell that floats with its wrist strap.
Its significance is as the definitive 1980s adventure film camera: cheap holiday snapshooter then, cult object now, feeding the film revival's appetite for waterproof point-and-shoots for pool parties, festivals and beach film photography — demand visible in the wide £86-£350 spread across 18 current UK listings.
UK used-buying checks: never trust three-decade-old waterproofing — the O-ring seals have almost certainly hardened, so treat any unit as splashproof at best until seals are inspected/greased, and ask whether it has ever flooded (check inside the film chamber for corrosion tide-marks); open the battery compartment (it takes two AA cells) and check the contacts, a common corrosion site on beach-used examples; fire the flash and cycle the 35/50mm lens switch; confirm the film door gasket is supple and the latch clamps firmly; and test motor advance with a sacrificial film. Boxed, unflooded examples justify the top of the price range; salty, scratched ones do not.
