The Pentax 110 is a subminiature single-lens reflex camera built around the 110 cartridge film format. It was introduced in the late 1970s as part of Asahi Pentax's Auto 110 system, which paired a compact SLR body with interchangeable bayonet-mount lenses.

Sales data is thin: a single UK auction hammer result from August 2024 saw a Pentax 110 sell for £227, and as of today that figure is the only saleroom datapoint we can cite for what one is worth. Because hammer prices reflect wholesale levels in the auction market rather than retail asking prices, dealer-listed examples often price higher, and condition together with the presence of original lenses materially affects value.
