Questions to Ask When Buying a Used Camera
For photographers buying a used body from a private seller, a marketplace listing or a used department. These 20 questions cover how the camera was used, shutter count, drops and moisture, sensor and viewfinder condition, autofocus and battery health, warranty and grey market status, and how to test it before you pay.
The questions
Open any question for the note
Why are you selling it, and what are you replacing it with?
Why ask it
Upgrading to a newer body in the same system is the ordinary answer and easy to believe. Someone selling a camera they bought two months ago, or replacing it with the identical model, is usually selling a specific problem rather than moving on.
How long have you owned it, and did you buy it new?
Why ask it
A second or third owner cannot tell you whether it was ever dropped, soaked or repaired, and the original receipt is what establishes any remaining warranty. If they bought it used themselves, ask what they were told at the time and whether they believed it.
What was it used for: family photographs, paid work, travel, video?
Why ask it
A body used for weddings has thousands of cycles and hard handling behind it, and one used for landscape work has fewer cycles but may have lived in cold, damp and dusty conditions. Neither is disqualifying, but they wear in different places and tell you where to look.
What is the shutter count, and how can I verify it?
Why ask it
On many bodies the count is embedded in the metadata of a recent file, so ask for an unedited JPEG straight out of the camera rather than a screenshot. On some brands only a service center can read it, in which case age and the condition of the grips and dials are your best proxy.
Has it ever been dropped, or been out in rain, dust or salt air?
Why ask it
Impact damage often shows up later as a misaligned mount or a focus system that is slightly off, and salt air corrodes contacts and screws from the inside. Look at the corners of the body, the tripod plate and the screw heads for the marks that answer this question independently.
Has it ever been serviced or repaired, and do you have the paperwork?
Why ask it
A documented sensor clean or shutter replacement is good news, because it resets the wear on the most expensive part. An undocumented repair by a non-authorized shop is the opposite, since mismatched parts and disturbed shims are what cause focus problems nobody can diagnose.
Is there any fungus, haze or debris visible in the viewfinder?
Why ask it
Fungus in a viewfinder is a storage problem: it grows in warm, humid, dark places and it can spread to any lens you mount. Dust in the finder is cosmetic and common, while a branching web pattern is a reason to stop and check where the gear has been kept.
What does a photograph of a plain white surface at a small aperture look like?
Why ask it
Ask for that exact frame, shot at f/16 or smaller against a wall or a bright sky, because it makes sensor dust and any oil spots obvious. Ordinary dust wipes off in a clean, but oil returning after each clean suggests a shutter or aperture mechanism problem.
Are there any dead or stuck pixels, and has anyone checked a long exposure?
Why ask it
Dead pixels show up as fixed colored dots in the same place on every frame and are most visible in a dark exposure of a few seconds with the lens cap on. Bodies can often map them out in firmware, so what matters is the count and whether they appear in clusters.
Does autofocus work in every mode and across the whole frame?
Why ask it
A single misbehaving focus point or an inaccurate phase detect module is a repair, not a setting, and it is easy to miss if you only shoot the middle of the frame. Test tracking, single point at the far edges, and eye or face detection if the body has it.
How many batteries come with it, are they genuine, and how are they holding up?
Why ask it
Third party batteries sometimes will not report health or work with in-camera charging, and an original battery several years old may hold a fraction of its rated shots. Check the battery information screen if the camera has one, and price replacements before you negotiate.
How worn are the grips, dials, mount and hot shoe?
Why ask it
Lifting rubber grips are cheap to replace but they tell you the camera has lived in heat and sweat, and a hot shoe with paint worn to bright metal means heavy flash use. A brassed lens mount and a polished tripod thread both indicate far more use than a low stated shutter count would suggest.
Do all the doors, covers and card slots close and latch properly?
Why ask it
Port covers and battery doors are the weather sealing on most bodies, and a torn cover or a loose card door turns a sealed camera into an unsealed one. Open and close each one yourself, and insert and eject a card from every slot several times.
Is the rear screen and the viewfinder display free of scratches, dead lines and dimming?
Why ask it
A dead row on an electronic viewfinder or a cracked screen makes the camera hard to work with and is often uneconomical to fix on an older body. Look at both against a bright and a dark scene, since a fault can hide in one and be obvious in the other.
What comes with it: box, charger, cables, strap, caps, manuals?
Why ask it
A charger and a body cap cost real money to replace, and the original box matters more than it should when you eventually resell. The presence of everything also suggests an owner who kept things carefully, which is weak but genuine evidence.
What firmware is on it, and does the manufacturer still support this body?
Why ask it
An outdated firmware version is a five minute fix, but a body the manufacturer has ended service support for cannot be repaired at any price once something fails. Check the current support status for the model before you buy an older camera to rely on.
Is there any warranty left, and was it bought from an authorized dealer in this country?
Why ask it
Manufacturer warranties are usually regional, so a grey market body may be refused service locally even when it is nearly new. Ask for the original receipt, since it is the only thing that transfers a warranty and the only proof of where the camera came from.
Has it been used for long video recording, and has it ever overheated or shut down?
Why ask it
Sustained recording heats a body far more than stills and some models throttle or stop as a result. If you plan to shoot video, ask for a specific answer about clip lengths and ambient conditions, since the general answer is always that it works fine.
May I test it with my own card and lens, and keep the files?
Why ask it
Bring a card, a lens you know well, and a laptop if you can. Taking the raw files home lets you look at sensor spots, corner sharpness and focus accuracy at full size, which is the check that finds problems a viewing on the rear screen never will.
What is your price, and how would you like to handle payment and shipping?
Why ask it
A seller pushing for an untraceable transfer, or refusing any platform that offers buyer protection, is telling you something before the camera arrives. For remote purchases, agree on insured shipping and a short inspection window in writing before you send money.
Testing a Used Camera Body
Practical guidance for the conversation itself
A Fifteen Minute Test in Person
- 1Put in your own card and your own lens, and shoot a plain bright wall or sky at f/16 to reveal sensor dust and oil.
- 2With the cap on, take a several second exposure at base ISO and look for stuck or hot pixels in the dark frame.
- 3Shoot the same scene at every aperture the lens has, listening for a hesitant or sticking aperture actuation.
- 4Focus on a high contrast edge with single point autofocus at the center, then at the far corners, and compare.
- 5Try continuous tracking on something moving toward you, and eye or face detection if the body has it.
- 6Fire a burst at the fastest frame rate for several seconds and listen for an uneven or laboring shutter.
- 7Cycle every dial, button and switch, including the ones you rarely use, and watch the display respond to each.
- 8Open and latch the battery door, card door and every port cover, and eject a card from each slot.
- 9Check the battery information screen if the body has one, and note whether the batteries are genuine.
- 10Copy the files to a laptop before you leave, or at minimum keep the card and review them at full size that day.
If You Are Buying Remotely
Ask for specific frames, not more product photographs
Request an unedited JPEG straight out of the camera of a white wall at f/16, a dark frame with the cap on, and a photograph of the sensor and the mount with a flashlight held at an angle. Sellers with nothing to hide send these within an hour. Sellers who send more glamour shots of the body instead have answered a different question.
Prefer a used department with a return window
A camera store's used inventory costs more than a private sale, and what you are buying with the difference is a stated condition grade, a short warranty and the right to send it back. For an expensive body, or a first camera in a system you cannot test lenses against, that protection is usually worth the premium.
Use a payment method with recourse and insured shipping
Agree in writing on who pays shipping, that the parcel is insured for the full value, and that you have a few days after delivery to test it. Any seller pushing for a bank transfer or a payment app without buyer protection is removing the only leverage you would have if the camera arrives faulty.
Test it the day it arrives
Run the whole in-person checklist as soon as you unbox it, including full size review of the files on a computer. Inspection windows are short and dispute processes reward whoever acted quickly, so do not leave the camera in the box until the weekend.
Red Flags
- Refusal to shoot a white wall at a small aperture or a dark frame on request.
- A shutter count claimed but never shown, on a body where the metadata would show it.
- Fungus in the viewfinder or on any lens the seller shows you, which points to how everything was stored.
- Oil spots that reappear on the sensor after cleaning.
- Repair work with no receipt, or a repair described as done by a friend.
- A body sold without a charger, cap or battery and no explanation of where they went.
- Screw heads on the base plate that are chewed or mismatched, which means the body has been opened.
- Pressure toward an untraceable payment, or refusal of any platform that offers buyer protection.
Costs to Add to the Purchase Price
- A spare genuine battery, since an original battery several years old rarely performs to specification.
- A professional sensor clean if the seller's white wall frame shows more than light dust.
- Cards, a card reader, and a charger if the original is missing.
- A body cap, a strap and a hood or cap for any lens included in the deal.
- Any accessory the system requires that you assumed was included, such as a proprietary cable or adapter.
- For an older body, a check on whether the manufacturer still services the model at all.
