In the 1960's making a photo was still surrounded with quite some technical knowledge. One had to understand shutterspeed/aperture combinations. Sensitivity of a film had to be set in ASA ( American Standard Association ) or DIN ( Deutsche Industrie Norm ) , ISO ( International Standard Organization ) values were not known. Colour film was still a second choice behind black and white film, which was available in a whole range of sensitivities and characteristics by many brand names.

Therefore it is not surprising that Rollei offered a fast range of accessories:
