Samsung's 8MP AA-battery compact from 2007 — 38-190mm 5x zoom, 2.5in LCD, SD cards.
The Samsung S850 was an 8-megapixel point-and-shoot in Samsung's AA-powered S-series of budget compacts, announced in January 2007 and shipped that spring at around $250. It sat above the S830 in the range, adding a longer 5x zoom, and was sold in black and silver finishes.
It paired an 8-megapixel CCD with a Samsung SHD-branded 5x optical zoom covering a 38-190mm equivalent range at f/2.8-4.4, focusing down to 1cm in macro mode. A 2.5-inch, 230,000-pixel LCD handled framing, ISO ran from 50 to 1600, shutter speeds spanned 15 to 1/2000 second, and Samsung's ASR shake reduction assisted longer exposures. Images stored to SD/SDHC cards plus internal memory, video recorded in MPEG-4 AVI, and power came from two AA batteries.
The long-for-its-era 5x zoom and simple scene-mode operation made it a family and holiday camera first. The AA power supply is a practical strength today, and the 1cm macro mode adds some close-up flexibility, though there is no optical stabilisation and high-ISO output from the small CCD is noisy, so it suits casual daylight shooting rather than low light.
On the used market the S850 benefits from AA power - no proprietary charger to hunt down - and standard SD cards, so a body-only purchase is usable immediately. Check the telescoping 5x zoom extends and retracts without grinding, look for LCD scratches and dead pixels, and confirm the battery-door catch is intact, a common weak point on AA compacts. CCD-era colour appeals to digicam collectors.
