The original Pen F was created in 1963 by Olympus' legendary designer – Yoshihisa Maitani. At the time, 35mm film and processing was considered quite expensive – so much so that Olympus was actively developing a line of “half frame” cameras, which yielded two shots on a standard 35mm frame and allowed the user to shoot 72 images on a standard 36-shot roll. The Pen F was a groundbreaking half-frame SLR that used an incredibly innovative body design in order to keep its size so compact. The mirror system used with the lens is recessed into the body – thereby avoiding the pentaprism “hump” that nearly every SLR camera has. A collection of small and truly excellent lenses – from an ultra-wide 20/3.5 to an impossibly rare 800/8 were developed alongside it. The Pen FT, introduced in 1966, included a built-in light meter
