Used-camera inspection
What to check before you pay
A clean, well-maintained older camera can be a better purchase than a newer body with hidden damage or an unclear history.
1
Shutter count
Use an original camera file whenever possible. Edited or exported images may no longer contain readable shutter metadata.
2
Sensor condition
Check for scratches, dust, hot pixels, banding, and unusual marks in evenly lit test images.
3
Autofocus and stabilization
Test multiple focus modes, subject detection, continuous autofocus, and IBIS with a known-good lens.
4
Card slots and ports
Confirm every card slot, USB port, HDMI port, microphone input, headphone output, and network connection.
5
Buttons and controls
Test every dial, joystick, button, touchscreen area, EVF sensor, and articulated-screen hinge.
6
Battery and accessories
Inspect the battery, charger, body cap, cables, strap mounts, and any included grips or adapters.

One final consideration
The better camera on paper may not be the better camera for you.
These scores reward clear, measurable advantages. They cannot fully account for ergonomics, menu preferences, existing lenses, current used prices, physical condition, or how a camera feels in your hands.
Treat the verdict as informed buying guidance—not a replacement for handling the camera yourself or evaluating the complete cost of the system around it.
Before you decide
- ✓Handle both cameras if possible.
- ✓Compare the lenses you would actually buy.
- ✓Check current new and used prices.
- ✓Consider condition, warranty, and shutter count.
