Overview
Older Japanese compact digital cameras have become popular again because they produce a distinctive early-digital look.
That popularity has also created a problem: clean-looking cameras are often listed at prices that assume full functionality.
For a digicam, appearance is not enough.

Confirm the exact model
Check manufacturer, model number, color, regional variant, included battery, included charger, and memory-card type.
Similar model names can use different batteries or storage formats.
Test the lens mechanism
Compact-camera lenses can fail even when the camera powers on.
Look for evidence that the lens extends and retracts, zoom works, autofocus works, and the shutter fires.
A camera stuck on startup can be difficult to repair.
LCD condition
Check for dead pixels, dark patches, yellowing, scratches, and display failure.
If the listing never shows the screen powered on, treat that as missing evidence.
Battery and charger
Older digicams often use proprietary batteries.
Confirm battery included, charger included, battery still charges, and replacement battery availability.
A cheap camera without the correct charger may become inconvenient or expensive.
Memory-card compatibility
Older cameras may use SD, miniSD, Memory Stick, xD-Picture Card, or CompactFlash.
Check the exact format before buying.
Flash and controls
Look for seller testing of flash, buttons, zoom lever, mode dial, card slot, USB port, and battery door.
Sample images
If a seller provides sample images, they can help confirm that the camera records files, focuses, and exposes reasonably.
Sample images still do not prove every function works.
