The Cyber-shot DSC-W520 was one of Sony's 2011 budget W-series compacts, slotting into the crowded W510/W520/W530/W550 cluster that Sony spread across markets and retailers that year. Like the W115 and W215 before it, it was a channel-specific model, so it drew little dedicated review coverage despite selling widely.
It used a 14.1-megapixel 1/2.3-inch Super HAD CCD with a 5x optical zoom covering 25-125mm equivalent at f/3.3-5.8, framed on a 2.7-inch LCD. Face detection, smile shutter and a built-in flash were included, startup took around 0.6 seconds, and the whole camera weighed roughly 108g at 96.5x55.9x20.3mm. Power came from a small rechargeable lithium-ion pack.
The useful 25mm wide end and 5x range in a sub-110g body make it a decent glovebox or handbag camera, and it is among the cheapest routes into the CCD compact look. It is an entirely automatic camera with no manual exposure control, and there is no optical stabilisation to help at the 125mm end.
These late CCD budget models are usually cheap, so condition matters more than rarity: check the lens extends cleanly, the flash fires and the screen is unscratched. The compact lithium-ion battery and its standalone charger are frequently separated from the camera — confirm both are present, as replacements can cost a meaningful share of the purchase price.
