Pentax Auto 110

The Pentax Auto 110 is the smallest single lens reflex camera ever made and the only camera with interchangeable lenses ever produced for the 110 film cartridge. A true camera system, the Auto 110 has six available lenses: 18mm, 24mm, 50mm, 70mm, 18mm fixed-focus, and 20-40mm zoom (all f/2.8), two external flashes, an electric film winder, and a slew of macro adapters, filters, diopters, and lens hoods. A third party 1.7x teleconverter was also produced by the German company Soligor.

Pentax P30T

The Pentax P30T is a plastic manual focus SLR spawned during the peculiar limbo period that took place after manufacturers began moving away from heavy, all-metal manual focus SLRs but before plastic autofocus cameras became the norm. The P30T differs from the base P30 and its other variants in that it has a plastic film door as well as a diagonally split focusing screen.
