The Steky is a subminiature camera produced by Riken Optical of Japan, designed to use 16mm film for compact, discreet photography. It was introduced in the postwar period and positioned as a pocketable alternative to full-size 35mm cameras of the era.

Sales data for the Steky is extremely limited, with a single recorded UK auction hammer result of £109 from 1998 — a wholesale saleroom figure rather than a dealer retail price. Because that record is decades old, it offers only a rough historical reference for what the Steky has sold for, and current values in today's market would need to be confirmed against more recent results before a buyer relies on any specific price.
