The Nikon Coolpix S225 is a slim digital compact from Nikon's S-series, released in 2009 as an easy point-and-shoot aimed at casual photographers wanting a pocketable everyday camera.
It has a 10-megapixel 1/2.3-inch CCD sensor behind a 3x optical zoom lens equivalent to roughly 35-105mm at f/2.9-5.8, a 2.5-inch LCD, and stores images on SD/SDHC cards, powered by a small rechargeable lithium-ion battery.
It shares its core specification with the sister Coolpix S220 but was sold with extra bundled internal memory in some markets, otherwise offering the same straightforward point-and-shoot handling with no manual exposure controls.
These simple compacts are inexpensive on the used market and suit buyers wanting a basic backup or first digital camera. It is worth checking the LCD for dead pixels, testing the zoom and autofocus, and confirming the battery still holds charge.
