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

, 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 18×24 mm vertical (

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

, 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.
