Catalog category
Electronics
Identify electronics by exact model, included components, testing status, and repair history.
Research principleIdentity before value
Small differences in release, condition, or included parts can create completely different comparable markets.
Identification workflow
Document the exact item
- Find the full model number rather than relying on appearance.
- Record power supplies, batteries, remotes, cables, lenses, and proprietary accessories.
- Describe what was actually tested and what remains unknown.
Value factors
Compare relevant evidence
- Tested working, powers on, untested, and parts-only are distinct conditions.
- Battery corrosion and missing proprietary accessories can dominate value.
- Compare the same model and configuration, including storage or lens variants.
