Olympus's 2004 easy-line Camedia — 3.2MP CCD, 38-114mm f/2.9-5.0 zoom, xD card; D-540 Zoom in the US
The Olympus Camedia C-310 Zoom of 2004 sat towards the bottom of what Olympus called its Easy category of digital compacts. The identical camera was sold as the D-540 Zoom in North America and as the X-100 in some other markets, so all three names turn up for the same body in used listings.
It pairs a 3.2-megapixel 1/2.7-inch CCD with a 3x zoom equivalent to 38-114mm at f/2.9-5.0. Exposure is via Digital ESP metering and scene modes only — no aperture or shutter priority — with auto ISO from 50 to 320. It has iESP contrast-detect autofocus with macro modes down to 2cm, a 1.8-inch 85,000-pixel LCD plus optical finder, TruePic Turbo processing, silent 320x240 QuickTime movies, and xD-Picture Card storage. It runs on two AA cells or a rechargeable lithium pack, with USB and PictBridge connectivity.
This is a pick-up-and-shoot camera for casual use: point, let the scene modes work, and enjoy the characteristic colour of an early-2000s Olympus CCD. Enthusiasts will find the lack of manual exposure and the modest ISO ceiling restrictive, and the small LCD takes some getting used to after modern screens.
The xD-Picture Card format is long discontinued, so confirm the slot reads a card and ideally buy one with a card included. AA power is a plus — no orphaned charger to hunt down. Test the lens extends and retracts smoothly, the flash charges, and the LCD shows no bleed; check the battery compartment for corrosion from old alkalines.
