Olympus's entry Camedia — 4MP CCD, fixed 37mm-equiv f/2.8 lens, xD + internal memory, AA power
The Olympus Camedia C-170 was an entry-level 4-megapixel digital compact announced in January 2005, sold in North America as the D-425. It sat at the very bottom of the Camedia range, aimed at first-time digital camera buyers on a tight budget.
It used a 4-megapixel 1/2.5-inch CCD behind a fixed 37mm-equivalent f/2.8 lens with no optical zoom, relying on digital zoom only. A 1.5-inch LCD handled composition, 14MB of internal memory was supplemented by an xD-Picture Card slot accepting cards up to 512MB, QuickTime movie recording was included, and power came from two AA batteries. Ten shooting modes covered portrait, landscape and night scenes.
With no optical zoom and minimal controls, the C-170 suits buyers wanting the plainest possible early-digital snapshot look, or collectors filling out the Camedia line. The fixed moderately wide lens actually encourages simple documentary-style framing, and AA power keeps it usable without hunting for chargers.
Second-hand checks are simple: confirm it boots on fresh AAs, look for battery-compartment corrosion, and verify the internal memory still saves and plays back images. xD cards are discontinued and pricey, though the 14MB internal store means a card-less example can still be tested and lightly used.
