Pentax Auto 110 Engineering Marvel
While 110 was mostly used in cheap plastic snapshot cameras, Pentax built a complete miniature SLR system (Pentax Auto 110) in 1978 with interchangeable bayonet lenses (18mm, 24mm, 50mm, 70mm), TTL metering, and motorized auto-winders that fit into the palm of a child's hand -- often cited as the smallest interchangeable-lens SLR system ever produced.
