Sony's 2010 entry compact — 12.1MP CCD, 4x 28-112mm zoom, takes SD and Memory Stick Duo
The Sony Cyber-shot DSC-W310 was the entry point of Sony's 2010 W-series compact range, announced in January of that year. It belongs to the first wave of Sony compacts to accept SD cards alongside the company's own Memory Stick format, which Sony rolled out across its 2010 line-up.
It combines a 12.1-megapixel 1/2.3-inch CCD with a 4x zoom starting usefully wide at 28mm equivalent (28-112mm, f/3.0-5.8). There is a 2.7-inch 230k-dot LCD, VGA 640x480 30fps video, and dual-format card support for SD/SDHC/SDXC and Memory Stick Duo. The NP-BN1 lithium-ion battery powers a body of about 137g; there is no optical stabilisation.
The wide 28mm end is handy for interiors and group shots, and operation is fully automatic point-and-shoot. It suits beginners and travellers wanting a light spare camera, though the lack of optical stabilisation shows at the telephoto end in dim light.
Used buyers have it easy on consumables: SD card support and cheap NP-BN1 replacement batteries and USB chargers. Check the lens for smooth extension, the screen for scratches, and shoot a telephoto test frame to confirm sharpness since there is no optical IS to mask shake. CCD-era colour is part of the appeal for retro digicam buyers.
