The Pentax Auto 110 is a subminiature single-lens reflex camera for 110 cartridge film, introduced by Asahi Optical at the end of the 1970s. Sold as an outfit, it was offered with interchangeable bayonet-mount lenses and accessories — unusual for the 110 format, which was otherwise dominated by simple fixed-lens snapshot cameras.

At recent UK auction, complete Pentax Auto 110 outfits have changed hands at hammer prices of around £60–£62, with both recorded sales clustered tightly in that band. Because these are saleroom hammer results rather than retail figures, dealer-listed kits today typically ask more, and condition of the lenses, finder and dedicated flash drives the value far more than the body itself sells for in 2026.
