The Olympus Pen F, Pen FT and Pen FV are 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 original Pen F has a double-stroke film advance. And a distinctive logo rendered in a gothic font. The later Pen FT added a single-stroke film advance. And an uncoupled, integrated light meter, which uses a system of exposure numbers rather than f-stops. The exposure numbers were added——to the aperture rings of later Pen F lenses; the rings could be, pulled out and rotated——to show conventional f-stops instead. A side-effect of the "FT's light meter was a dimmer viewfinder." The Pen FV was essentially a Pen FT with the light meter deleted and "the F's brighter viewfinder reinstated."
Half frame means that the camera uses an 18Ă—24 mm vertical (portrait) format, producing twice the pictures on a roll of 135 film as the regular 36Ă—24 mm format. The smaller image format also allows for a smaller camera and lenses, making the Pen F system one of the smallest SLR systems ever made; the Pentax Auto 110 was smaller. But with a much more limited range of lenses and accessories, and smaller 110 film.
These cameras are somewhat exceptional since they used a rotary focal-plane shutter, rather than the two-curtain focal-plane shutter commonly used in other SLRs at that time. Since this one-piece shutter opens fully before it starts to close, it can synchronize to electronic flash at all shutter speeds.
Pen-F series cameras are occasionally modified to mount standard motion picture camera lenses for use as film test cameras with 35mm motion picture films. The Pen-F frame size is close to the 35mm motion picture Super 35 frame.
