Samsung's 5MP Digimax compact — 35-105mm-equiv f/2.8-4.8 zoom, 2.5in LCD, AA power, from 2005.
The Samsung Digimax A50 was a 5-megapixel compact in Samsung Techwin's Digimax A-series, announced in 2005. It sat above the 4-megapixel A4 in the budget line-up, offering a bigger screen and slightly brighter lens while keeping the same simple, AA-powered formula for family snapshot duty.
It combined a 5-megapixel 1/2.5in CCD (2592x1944 maximum resolution) with a 3x optical zoom covering a 35-105mm equivalent range at f/2.8-4.8, plus 4x digital zoom. A relatively large 2.5in 200k-dot LCD handled framing. Sensitivity ran ISO 50-400, shutter speeds spanned 15sec to 1/1200sec, and macro focusing reached to around 5cm. Storage was SD or MMC, and power came from two AA batteries. The body weighed roughly 120g.
It suits casual shooters and digicam collectors after mid-2000s CCD colour in a simple package. The long 15-second maximum shutter is unusual at this level and allows basic night experiments on a tripod, though the ISO 400 ceiling and small sensor keep it a daylight camera at heart.
Used prices are low, so condition matters more than spec. Check the battery compartment for alkaline leak corrosion, confirm the SD/MMC slot reads cards, and watch for lens errors when the zoom extends. Inspect the 2.5in screen for scratches and dead pixels, and test flash recycle — a fresh set of NiMH AAs makes the most reliable test.
