The Asahi Pentax *istDS is a digital SLR introduced in the mid-2000s, aimed at enthusiasts moving from film to digital. It used the Pentax K-mount, allowing it to accept a wide range of existing Pentax lenses, and was positioned as a compact, entry-to-mid-level body when new.

Sales data for the *istDS is thin: a single UK auction hammer result in March 2025 saw a body sell for £62. With only one wholesale auction data point on file, today it is difficult to give a reliable price range, and what a *istDS is worth in 2026 depends heavily on whether a kit lens, charger and battery are included.
