Sony's slim 2010 budget compact — 14.1MP CCD, 26-105mm 4x zoom, SD or Memory Stick, 17mm-thin body.
The Sony Cyber-shot DSC-W320 was an entry-level slimline compact introduced in early 2010, one step above the DSC-W310 in Sony's crowded W-series of that year. It packed a high pixel count and a usefully wide lens into a very thin body at a budget price, aimed squarely at casual point-and-shoot buyers.
It used a 14.1-megapixel 1/2.3-inch CCD producing images up to 4320x3240, with a 4x zoom covering a 26-105mm equivalent range at f/2.7-5.7, wider at the short end than most rivals. The 2.7-inch LCD had 230,400 dots, video was limited to VGA 640x480 at 30fps, and features included face detection and Smile Shutter. Storage took SD/SDHC/SDXC as well as Memory Stick Duo, power came from the small NP-BN1 battery, and the body measured just 93x52x17mm at 117g.
The W320 suits buyers wanting the thinnest, simplest sort of 2010-era digicam, with the 26mm-equivalent wide end handy for interiors and group shots. It lacks optical image stabilisation and HD video, which its W350 sibling added, so it is best kept to good light and steady hands; the trade-off is a genuinely shirt-pocketable camera.
Used examples should be checked for a healthy NP-BN1 battery, though this cell was fitted to huge numbers of later Cyber-shots and cheap replacements are common. The SD card slot removes any Memory Stick dependency. Inspect the sliding lens cover area and barrel for dents from pocket carry, confirm the flash charges, and look for the corner sharpness issues typical of very thin high-resolution CCD compacts.
