Canon K-35 MkIV 50mm T1.3
Summary
After 1982, the 55mm T1.3 was changed to the 50mm T1.3, based on the 50mm FD-L f/1.2 still lens, which could be considered as part of a quasi MkIV set which also introduced revised barrel designs with glow-in-the-dark focus and iris scales as well as native PL mounts to the set.
Developed as part of a research program jointly carried out by Canon Inc. and Cinema Products Corporation, in cooperation with the Research Center of the Association of Motion Picture and Television Producers, the Canon high speed aspheric lenses were especially designed to meet the critical tolerances required for professional 35mm cinematography.
