Checklist to Know Before Buying a Used Camera | Knowledge #220

We previously introduced tips for smartly choosing a used camera in our magazine.

As a follow-up, we present key points to check before purchasing. Don't be complacent just because it looks nice; use this checklist to avoid regrets.

Used cameras often have issues that only become apparent when shooting. Before purchasing, take test shots and check the following points:

• Shoot the sky or a white wall: Dust on the image sensor will appear as black spots
• Shoot in dark places: Check for excessive noise at high sensitivity
• Check autofocus: Ensure it operates accurately without hesitation
• Try continuous shooting: Check for smooth shutter operation and absence of strange noises

Pay special attention to image sensor dirt, as repair costs can be high.

Shutter count is a crucial indicator of a camera's usage frequency. Like a car's mileage, approaching the durability limit increases the risk of failure.

• Below 50,000: Almost like new
• 50,000–100,000: Typical usage range
• Above 100,000: Higher risk of failure, caution advised

Shutter count can be checked via the camera's settings, dedicated software, or online tools. It's also recommended to inquire with the seller beforehand.

The battery is one of the most prone to degradation in used cameras. Rapid battery drain can lead to power loss during shooting.

• Check 'Battery Degradation' in settings (if supported)
• Test shooting count and video recording time after full charge
• Check for spare batteries

Also, ensure all accessories are included.

• Genuine charger (compatibles may cause issues)
• Body cap and strap (missing items may require separate purchase)
• Manual and warranty (enhances resale value)

• Conduct test shots to check for sensor dirt or malfunctions
• Check shutter count to ensure it's not nearing the durability limit
• Verify battery degradation and check for spare batteries
• Ensure all accessories (charger, cap, strap, manual) are included

Using this list will make it easier to choose a used camera without regrets. Refer to our previous article for more guidance.
