The
Olympus Pen F,
Pen FT and
Pen FV were very similar half-frame
35 mm single-lens reflex (SLR)
cameras with interchangeable lenses produced by
Olympus of
Japan between 1963-1966 (Pen F), 1966-1972 (Pen FT) and 1967-1970 (Pen FV). The chief difference between them was that the Pen FT had an integrated
light meter, while the F and FV did not.
