Pentax's 2005 entry-level 5MP compact - 3x zoom, AA batteries, SD storage, 1.8-inch screen.
The Pentax Optio 50 was an entry-level 5-megapixel compact announced in February 2005, designed for beginners and casual photographers moving into digital. It anchored the bottom of Pentax's Optio range that year, below the 6-megapixel Optio 60 that followed a few months later, and is distinct from the related Optio 50L.
It offers 5 megapixels of resolution with a 3x optical zoom, up to 4x digital zoom, and a macro mode focusing as close as 6cm. Framing uses a 1.8-inch 130,000-pixel TFT LCD, movies record at 320 x 240 pixels, and the flash includes auto and red-eye reduction modes. Images save to SD cards or roughly 12MB of internal memory, power comes from two AA cells, and the body measures 91 x 61 x 27mm at about 130g.
As a true entry-level model it appeals today mainly as a cheap, pocketable CCD-colour experiment - it asks nothing of the user beyond pointing and shooting. The small low-resolution screen and modest movie mode date it, and low-light performance is limited, so treat it as a daylight snapshot camera.
Because it runs on AA cells and SD cards, revival is usually trivial: fresh NiMH batteries and a small pre-SDHC card cover it. Check the battery door latch and contacts for corrosion, confirm the zoom extends and retracts cleanly, and verify images are free of CCD banding or colour smears.
