Olympus Pen EES (1962)

Launched in 1962, the Olympus Pen EES was the world's first camera with a programmable EE shutter. The shutter speeds were 1/30 and 1/250 sec. The shutter speed changed automatically according to light level, thus increasing the appropriate exposure range. A three-zone focus system was used to adjust the focal point. The Olympus Pen EES heralded the start of the programmable EE camera boom.
