Casio Exilim EX-Z55 belongs to Casio's Exilim compact family: slim, easy to carry, and often interesting for people who want a pocket camera that feels different from the usual Canon ELPH or Sony Cyber-shot choices.
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 Casio model-specific rechargeable Li-ion 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 Casio Exilim / QV models plus Canon, Nikon, and Sony pocket compacts. A complete battery and card setup is usually more important than a tiny spec difference.
