The Sony Cyber-shot DSC-W120 is an entry-level pocket compact announced in January 2008 as part of Sony's high-volume W series. It was sold in several colours and became one of the most common point-and-shoot cameras of its generation, which is reflected in how frequently it appears on the UK second-hand market today.
It carries a 7.2-megapixel 1/2.5-inch CCD sensor behind a Carl Zeiss Vario-Tessar 4x optical zoom of roughly 32-128mm equivalent, with Super SteadyShot optical stabilisation. Features include a 2.5-inch LCD plus a small optical viewfinder, face detection with Smile Shutter, ISO up to 3200, and VGA 640x480 video. Storage is Memory Stick Duo or PRO Duo, and power comes from the rechargeable NP-BG1 lithium-ion battery.
For UK used buyers the W120 is a cheap and cheerful entry into the current wave of interest in late-2000s CCD compacts, whose colour rendering and small-sensor look have found a new audience. With around twenty live UK listings at any time it is easy to find, prices are low, and the NP-BG1 battery remains readily available new, which is not true of every camera from this period.
The main used-buying checks are the lens and storage. Make sure the lens extends fully without error messages, as gear faults are the common failure, and check the CCD for purple smearing or dead lines, since some sensors of this era degrade. Remember it takes Memory Stick Duo rather than SD, so budget for a card or a card adapter if one is not included, and confirm the battery holds a usable charge. Screen scratches are frequent but rarely affect function.
