Olympus Pen EED

The original Pen was introduced in 1959. Designed by Maitani Yoshihisa,[1] it was the first half-frame camera produced in Japan. It was one of the smallest cameras to use 35mm film in regular 135 cassettes. Its name comes from the idea that the camera was as portable as a pen. The concept was soon copied by many other Japanese makers. The Pen EE-D, produced from 1967 to 1972, is a more expensive automated-exposure model, with a CdS meter, a focusable 32mm f/1.7 lens and a hot shoe. Film speeds were 12-500 ISO. The EE-D were wider than the typical EE camera.
