HP's 5MP Photosmart compact — 1/2.5in CCD, 38-106mm equiv zoom, 1.7in LCD, SD storage, AA power, 2006.
The HP Photosmart M425 was a 5-megapixel compact announced at CES in January 2006, an entry-level model in the Photosmart M-series below the M525 and M627. It was pitched at first-time digital camera buyers during HP's brief period as a camera maker, with heavy emphasis on one-button print ordering and sharing.
It uses a 5-megapixel 1/2.5in CCD (2592x1936 effective) behind a 3x optical zoom spanning a 38-106mm equivalent range, framed on a 1.7in LCD. Storage is 16MB of internal memory plus an SD card slot, and HP's user guide specifies AA batteries for power. In-camera red-eye removal and the Photosmart Express button for print orders and sharing were the headline features.
It is about as simple as mid-2000s digital photography gets, which is now its charm: a small, slow, fully automatic compact with CCD colour, cheap to buy and easy to feed with AAs and SD cards. The 1.7in screen is cramped for composing and reviewing by any modern standard.
Corroded AA contacts and worn battery-door catches are the usual faults, so inspect both, and check the small LCD for delamination or scratches. Large SDHC cards may not be recognised, so use a modest-capacity SD card; otherwise there are no proprietary consumables to worry about.
