The Minolta Sportsfinder is an original optional accessory for the Minolta Weathermatic A, a waterproof 110 film camera introduced in 1980. This external finder makes framing photographs easier when shooting underwater with a diving mask, when using the camera's regular viewfinder is impractical.
It attaches to the rear of the camera using a clamp mount. An interesting original accessory for owners and collectors of the Minolta Weathermatic A.
