Sony's slim 2011 compact — 16.1MP CCD, Zeiss 5x 25-125mm zoom, Optical SteadyShot, 720p video, SD support.
The Sony Cyber-shot DSC-W570 was a slim 2011 W-series compact, sitting near the top of that year's budget line-up between the 4x DSC-W550 and the larger-screened DSC-W580. It squeezed a 16-megapixel sensor and a 5x wide-angle zoom into a body just 19mm thick, aimed at snapshooters upgrading from older 3x compacts.
It used a 16.1-megapixel 1/2.3-inch Super HAD CCD behind a Carl Zeiss Vario-Tessar 5x zoom spanning 25-125mm equivalent at f/2.6-6.3, with Optical SteadyShot stabilisation. Framing was on a 2.7-inch 230k-dot LCD. ISO ran from 80 to 3200, Sweep Panorama and Smile Shutter were included, and video recorded 1280x720 at 30fps. It accepted SD/SDHC/SDXC as well as Memory Stick Duo, with the small NP-BN1 battery rated at about 220 shots. Ready to shoot it weighed roughly 116g.
This is a straightforward pocket camera for daylight snapshots, travel and quick panoramas, with a usefully wide 25mm setting for interiors and streetscapes. The bright f/2.6 wide end helps indoors, but the lens slows to f/6.3 at telephoto, the dense CCD is at its best at low ISO, and there are no manual controls.
Used buying is low-risk on media — standard SD cards work fine. The NP-BN1 battery's 220-shot rating means a spare is worth having; cells and USB chargers are cheap. Check the lens extends and retracts cleanly, test SteadyShot at 125mm, and look over the slim shell for dents that can misalign the barrel.
