When digital still cameras first seriously arrived in the latter 90s there was a brief, half page article in one of the photo magazines showing what looked to be a film cassette with a few inches of film protruding. It was, in fact, a 'cassette' that was actually a digital capture medium, honed and sculpted to fit traditional 35mm cameras.

Then there was nothing else ever said. It was as if the digital manufacturers silenced this threat on the market for new digital cameras because the old film cameras (and their accompanying lenses) would have provided photographers with the ability to do quality digital photography without the consumer having to buy new equipment. - David Lyga
