Owner note

Why people still want it

Pentax Optio A20 is part of Pentax's Optio compact family: small, approachable, and often less over-hyped than Canon or Sony pocket models. The best listings are the ones with clear working proof and an easy battery/card setup.

Before you overpay

Check that the lens extends and retracts smoothly, flash fires, screen is readable, buttons respond, and the battery door closes firmly. Confirm Pentax model-specific rechargeable battery, the charger or AA plan, and SD/MMC card, Internal before comparing prices.

Best use

Best for casual snapshots, daylight walks, simple flash photos, and anyone who wants a real-camera feel without a complicated setup.

What to compare

Compare it with nearby Pentax Optio models plus Canon ELPH / IXUS, Nikon COOLPIX, and Sony Cyber-shot pocket cameras. A complete working kit usually beats a better-looking model name.
