Used cameras are a good value option, but choosing poorly can mean ending up with a problematic unit. This article covers 7 points you should check before making a purchase.
1. Shutter Count
Think of it like the mileage on a car — lower is better. Most DSLR/Mirrorless cameras have a shutter lifespan of around 100,000–400,000 actuations. Always ask to see the count before buying.
2. Sensor Condition
Take a photo of a white surface at a narrow aperture (f/16–f/22) and check for dust spots or scratches on the sensor. Dust can be cleaned, but scratches are hard to fix.
3. Lens Fungus or Haze
Shine a light through the lens to see if there is fungus, haze, or unusual dust inside. Fungus spreads and degrades image quality.
4. Button and Screen Function
Press every button, rotate the rings, and check the LCD screen and viewfinder for dead pixels.
5. Completeness of Accessories
Battery, charger, strap, box, and warranty card (if available) — having everything helps with resale value later.
6. Signs of Impact or Water Damage
Look around the edges and screws for dents, heavy scuffs, or rust stains, which indicate rough use or water exposure.
7. Buy from a Trustworthy Shop
Choose a shop that lets you inspect the condition beforehand, provides after-sales support, and answers questions clearly. It's safer than buying from a stranger.
At 247IT2U, we let customers inspect the condition before deciding, and we disclose the true condition of every unit. Feel free to ask about models you're interested in via Line.
