Why buy refurbished?
For three honest reasons: price (between 20 and 40% below new on high-end models), sustainability (keeping a body in circulation avoids manufacturing a new one and all its waste), and transparency: every unit has its own serial number, visible shutter count and inspection date.
Market depreciation does not affect optical or electronic performance. A well-kept, inspected item performs exactly like a new one.
