Olympus's 2007 weatherproof style compact — 8MP, 5x 36-180mm zoom, sold in Europe as the Mju 820 Digital.
The Stylus 820 was introduced in August 2007 as part of Olympus's style-led compact line, sold in Europe as the Mju 820 Digital. It carried the weather-resistant body concept the Mju/Stylus family was known for into an 8-megapixel generation, reaching shops from September 2007 at around £180 in colours including black, silver, red and blue.
An 8-megapixel 1/2.3-inch sensor sits behind a 5x optical zoom equivalent to 36-180mm, a longer range than most slim compacts of its day. The 2.7-inch, 230,000-dot HyperCrystal LCD handles framing, sensitivity runs ISO 50-1600, and face detection with Smile Shot and Shadow Adjustment Technology were the headline processing features. Movies record with sound at up to 640x480 and 30fps, and storage is xD-Picture Card backed by roughly 47MB of internal memory; panorama stitching requires an Olympus-brand xD card.
This is an easy, weather-resistant everyday compact for casual shooters, with the 180mm-equivalent reach giving useful framing flexibility on holiday. It is fully automatic, so there is nothing for photographers wanting manual exposure, and telephoto shots in dim light test the small sensor.
Check the seals around the battery and card door, since the weatherproof claim depended on them and they age. The camera uses discontinued xD-Picture Cards, so a bundled card adds real value, and confirm the proprietary lithium-ion battery still charges. LCD condition matters as there is no optical finder, and CCD-era colour is part of the appeal for current buyers.
