Olympus's 4MP Camedia compact — 3x 35-105mm zoom, xD card, AA or CR-V3 power; sold as D-565/X-300
The Olympus Camedia C-450 Zoom was a 4-megapixel consumer compact announced by Olympus Europe in August 2003. The identical camera was sold as the D-565 Zoom in North America and the X-300 in Japan, so all three names refer to one model.
It offered a maximum resolution of 2288x1712 pixels from its CCD, through a 3x zoom of 5.8-17.4mm f/3.1-5.2 equivalent to 35-105mm, with 4x digital zoom on top and a 20cm macro mode. Storage was xD-Picture Card (16-256MB officially supported), and power came from one CR-V3 lithium pack or two AA alkaline or NiMH cells; zinc-carbon cells are explicitly unsupported.
As a shooter it is a typical early-2000s family compact: simple automation, an optical viewfinder backed by a small LCD, and a usefully wide 35mm-equivalent starting focal length that many rivals lacked. It suits beginners exploring early CCD colour rendering on a small budget.
Check that the seller includes a working xD card, since the format is discontinued and cards are expensive; original 16-256MB cards suit it best. Test both battery options if possible, inspect for corrosion in the AA compartment, and cycle the zoom through its range to catch gear-train wear.
