Introduced in 1979, the Pentax Auto 110 holds the record as the smallest interchangeable-lens single-lens reflex camera ever produced. Despite using the humble 110 cartridge format, Pentax built out a genuine seven-lens system for it, with focal lengths ranging from a 18mm fisheye to a 70mm telephoto. The camera operates program-only exposure with TTL metering and a bright pentaprism viewfinder in a body small enough to fit in a shirt pocket. It was marketed as a serious miniature system, not a toy, and earned a German IF Design Award in 1980.

Pentax announced the Auto 110 system at Photokina 1978 and began shipping in 1979. The original system comprised seven lenses: 18mm f/2.8 fisheye, 24mm f/2.8, 50mm f/2, 70mm f/2.8, and zoom options including a 20-40mm f/2.8 and 50-110mm f/4. Accessories included dedicated flash units, a motor winder, and a right-angle finder. The Auto 110 Super followed in 1982, adding a built-in flash and self-timer. Production wound down around 1986 as 110 film availability declined. Kodak formally discontinued 110 film in 1982, though it lingered in some markets; Lomography revived it in 2012.
The Auto 110 demonstrated that a true SLR system - pentaprism, interchangeable lenses, TTL metering, genuine depth-of-field preview from through-the-lens viewing - could be miniaturized to pocket scale. Its engineering achievement influenced subsequent miniaturization efforts in camera design. The camera won a German IF Design Award in 1980 and was exhibited at industrial design shows as a product design milestone.
In practical terms, 110 film produces a 13x17mm negative, which is substantially smaller than 35mm (24x36mm), so image quality was always limited compared to full-frame 35mm. The Auto 110 was never a working photographer's tool in the way the Pentax LX was. Its significance is architectural and collectible rather than practical.
The Pentax 110 mount is proprietary and unique to this system. The seven-lens lineup:
Accessories: Winder 110, Flash AF100, Flash AF130, right-angle finder. All accessories are proprietary to the 110 system.
