OLYMPUS PEN F (1963) The Olympus Pen F was the world's first and only half-frame system single-lens reflex camera, released in 1963. The camera featured a porro-prism finder and was the first to have a rotary titanium shutter. It could be used with a highly versatile range of 20 exchangeable lenses. The Olympus Pen F was a revolutionary camera packed with innovative features. The rotary shutter, which combined speed with durability, was reportedly perfected only after long and hard effort by Olympus engineers.

Many professional features were packed into its compact body, including a high-performance F1.9 large-aperture lens, a high-speed 1/500 sec. shutter, and a built-in exposure meter that allowed direct reading of the LV.
