Mosaic mural from 1966 photographed with my 1966 Agfa Optima Rapid 250V on expired Trekpleister DX 100 (bought for € 0,25 at a flea market, the film that is, not the camera which was a full € 2,- at another flea market).
Using 135 film in a Rapid cassette involves cutting of a length of film and transferring it into the Rapid cassette in complete darkness. Film transport is no problem and you get nice square 24 x 24 mm negatives, but the developing lab sometimes cuts up your negatives because they don't expect this format anymore.
