Secondhand Camera Checklist: What to Check
When buying a used camera, you should check the shutter count, sensor for dust or scratches, lens glass for fungus and haze, all buttons and dials, the LCD screen for dead pixels, the battery compartment and contacts, the memory card slot, and the camera’s physical condition for dents or signs of a drop. This article walks through each check in detail so you can avoid costly repairs and know what to look for before handing over money.
Why Buy a Secondhand Camera?
Buying a used camera is a common way to save money or get a higher-end model than your budget would allow new. Camera bodies and lenses are precision instruments, but they are also durable and can last for years with proper care. Many photographers sell perfectly good gear when they upgrade, and the secondhand market is full of excellent deals. However, the savings come with risk: a camera may have hidden problems that aren’t obvious from a quick look. Knowing what to check helps you separate a good deal from a money pit.
Before You Meet the Seller
Start by asking the seller for the shutter count and any service history. A shutter count is the number of times the shutter has been fired, and it’s a good indicator of wear. Most consumer cameras are rated for 100,000 to 200,000 actuations, but professional models often last longer. Ask for clear photos of the camera from all angles, including the lens mount and sensor. If the seller is vague or refuses to provide a shutter count, that’s a red flag.
Physical Condition and Build
When you meet, examine the camera body for dents, scratches, and signs of a drop. A drop can misalign internal components even if the exterior looks fine. Check the tripod mount for wear—a heavily used mount suggests the camera was used professionally. Look at the rubber grips and eyecup; worn rubber is normal on an older camera, but peeling or missing rubber may indicate heavy use. Open the battery compartment and check the contacts for corrosion (white or green powder). Corrosion can cause electrical problems and is difficult to clean.
Sensor and Viewfinder Checks
Turn the camera on, set it to manual mode, and take a photo of a plain white surface (like a piece of paper) at a small aperture (f/16 or smaller). Then zoom into the image on the LCD and look for dark spots or lines. Those are dust or, worse, scratches on the sensor. Dust can be cleaned, but scratches are permanent. Also check the viewfinder: look through it at a bright, even surface. You should see the focus screen clearly, with no large black spots or cracks. A few tiny dust specks in the viewfinder are normal, but large marks could be on the focus screen or mirror.
Lens Inspection
If you’re buying a body with a lens, inspect the lens carefully. Look at the front and rear glass elements for scratches, chips, or cracks. Hold the lens up to a light and look for fungus (spider-web like patterns) or haze (a milky film). Fungus can spread and ruin a lens, and cleaning it is expensive. Check the aperture blades by setting the lens to manual aperture and looking through it as you move the aperture ring—blades should move smoothly and form a clean opening. Also check the autofocus by focusing on a distant object; it should be quick and quiet. Listen for grinding or hesitation.
Controls, Buttons, and LCD
Test every button, dial, and switch on the camera. This includes the shutter button, mode dial, exposure compensation, menu navigation, playback, and any custom buttons. A sticky or unresponsive button can be a sign of spilled liquid or wear. Check the LCD screen for dead pixels (black or white dots that stay constant) by displaying a blank image and looking closely. Dead pixels are not always a dealbreaker, but they can be annoying. Also check the screen for scratches; a screen protector is cheap, but a cracked screen is expensive to replace.
Battery and Charger
Ask to test the camera with a fully charged battery. Insert the battery and make sure it clicks in properly. Turn the camera on and check that the battery indicator shows a full charge. If the camera doesn’t turn on, it could be a dead battery or a more serious electrical issue. If the seller provides a charger, check that it works and that the battery charges. If you’re buying a camera that uses a proprietary battery, factor in the cost of a new battery if the included one is old or worn.
Memory Card and Transfer
Insert a memory card (bring your own) and take a few test shots. Review the images on the camera and then transfer them to your phone or computer if possible. This checks that the card slot works and that the camera writes data correctly. Also check that the card door closes and latches securely. A loose card door can cause the camera to lose connection and corrupt images.
Shutter Count and Wear Indicators
If the seller didn’t provide a shutter count, you can often find it in the camera’s menu (for some models) or by using free software on a test image. For example, on many Canon cameras, the shutter count is in the file name, while Nikon and Sony cameras may require software like Opanda or a web-based tool. A high shutter count (over 100,000) isn’t necessarily bad, but it means the camera has been used heavily and may need a shutter replacement sooner. Also check the rubber on the back and the mode dial—these wear out with use and can indicate how much the camera was used.
Common Problems to Watch For
- Error messages like “Err 01� or “Lens not detected� can indicate communication issues between the body and lens.
- Shutter lag or a shutter that doesn’t fire consistently suggests a worn shutter mechanism.
- Hot pixels in long exposures (red or blue dots) are common and usually not a problem, but a cluster of them could be a sensor issue.
- Autofocus issues such as hunting or not locking can be a sign of a dirty lens contact or a failing focus motor.
- LCD flickering or a screen that goes black intermittently may indicate a loose ribbon cable.
What to Ask the Seller
- Why are you selling it?
- Has it ever been dropped or exposed to water?
- What is the shutter count?
- Has it been serviced or repaired?
- Do you have the original box, manuals, and accessories?
- Can I test it before buying?
Price and Negotiation
Research the current market price for the same model in similar condition. Check online marketplaces and camera forums to get a range. If the camera has a high shutter count, visible wear, or minor issues, use that to negotiate a lower price. Be prepared to walk away if the seller won’t budge and the camera has significant problems. Remember that a good deal is only good if the camera works reliably.
Frequently Asked Questions
What is a good shutter count for a used camera?
There’s no single number, but a shutter count under 50,000 is considered low for most consumer cameras. Many cameras are rated for 100,000 to 200,000 actuations, so a count under 100,000 is generally safe. However, a well-maintained camera with 150,000 actuations can still work fine. The shutter count is just one indicator of wear—check the overall condition too.
Can I clean the sensor myself?
You can use a blower to remove loose dust, but for stubborn spots, it’s best to have a professional clean it. Sensor cleaning kits are available, but if you’re not confident, you risk scratching the sensor or leaving residue. A sensor with a few dust spots is normal and can be cleaned, but scratches are permanent and may affect image quality.
How do I check for shutter count on a used camera?
Some cameras display the shutter count in the menu, but most require software. You can take a photo and upload it to a free online shutter count tool that reads the EXIF data. For Canon, the shutter count is often in the file name (e.g., IMG_1234.jpg), but you may need to decode it. For Nikon and Sony, tools like Opanda or ShutterCount work on a computer.
Is it safe to buy a camera with a few dead pixels on the LCD?
Dead pixels on the LCD are cosmetic and don’t affect image quality. They are common and usually not a reason to reject a camera if the price is right. However, if the dead pixels are in the viewfinder or on the sensor, that’s more serious.
Can I return a used camera if it has problems?
It depends on where you buy. From a private seller, you typically have no warranty and no return policy. From a retailer that sells used gear, you may have a short return window or a warranty. Always ask about the return policy before buying, and get a receipt if possible.
What should I do if the camera has fungus on the lens?
Fungus can be cleaned, but it’s a delicate job that often requires professional service. If the fungus is minor and the price is low, you might consider it, but factor in the cleaning cost. If the fungus is extensive, it can etch the lens coating and permanently degrade image quality, so it’s usually best to pass.
