The Pentax Auto 110 is a subminiature single-lens reflex camera using 110 cartridge film, introduced by Asahi Optical at the end of the 1970s. It was positioned as a pocketable interchangeable-lens SLR system, offered with a small range of dedicated bayonet-mount lenses and a clip-on winder.

Sales data for the Auto 110 is extremely thin: a single recorded UK auction-hammer result of £94 from 2000 is the only data point available, so a current price range cannot be reliably stated for today's market. Buyers researching what the Pentax Auto 110 is worth in 2026 should treat that figure as historical only and look for fresh comparable saleroom results before committing, as condition, completeness of the system (body plus lenses and winder) and working electronics all materially affect value.
