Sony's upper-mid 2008 W-series compact — 10.1MP CCD, 5x 28-140mm Zeiss zoom, optical SteadyShot
The Cyber-shot DSC-W170 was the upper-mid model of Sony's 2008 W-series compacts, sitting above the W120 and W150. Its selling point over cheaper W models was a 5x zoom starting at a genuinely wide 28mm equivalent, at a time when most rivals began at 35mm.
It paired a 10.1-megapixel 1/2.3in Super HAD CCD with a Carl Zeiss Vario-Tessar 5x zoom equivalent to 28-140mm at f/3.3-5.2, stabilised by optical Super SteadyShot. It offered ISO 80-3200, face detection and Smile Shutter, a 2.7in 230,000-dot LCD plus a small optical viewfinder, and VGA MPEG1 movies. Storage was Memory Stick Duo/PRO Duo with 15MB internal memory; the NP-BG1 battery was rated at 390 shots, and the body weighed 142g.
It makes a tidy travel and everyday compact from the late CCD era, with the wide lens useful for landscapes and interiors. The optical viewfinder, unusual at this level, helps in bright sun. Controls are simple auto-oriented fare with no manual exposure modes.
Used examples are plentiful and cheap. The NP-BG1 battery was used across many Cyber-shots so spares are easy to find, but Memory Stick Duo cards are an obsolete format — check one is included. Test the stabiliser, look for scratches on the small lens cover and LCD, and check the telescoping zoom extends smoothly without error messages.
