During some recent internet roaming, I stumbled across some information about this camera and it was an instant had-to-have response. The smallest SLR camera system ever? Who could resist that?
Back in 1978/1979 when the Pocket Instamatic format was already losing popularity, Pentax came out with their first (and only) 110-format camera. They only made one, but they made it count! This is no simple one-speed one-aperture point-and-click plastic job. No way. This is a complete camera system.
Single Lens Reflex body, interchangable lenses, filters, dedicated electronic flash units, and motorized power winders… the Pentax Auto 110 was a full-fledged system camera, for a sub-miniature plastic cartridge format.
How small is it? In the image above, you can see the camera along with two spare lenses, a film cartridge, and for a sense of scale, a quarter. The camera and a couple lenses can fit in a jacket pocket. The camera and a couple lenses are smaller than most 35mm SLR bodies. Amazing.
