Olympus FTL M42 system


35mm SLR system consisting of the Olympus FTL camera with M42 screw mount and a small line of Zuiko lenses. It was announced in July 1971, but replaced by the Olympus system with the OM bayonet mount already in January 1972. Thanks to a slightly modified mount, FTL provided TTL exposure metering at full aperture with Zuiko M42 lenses, and stop-down metering with other M42 lenses. According to Olympus, it was the world's first Praktica mount SLR camera with full open light measuring system.
