Every used-camera listing looks like a bargain until you hold the thing. The photos are bright, the price is 40% under new, the seller is 'selling because I upgraded' – and three weeks later the autofocus hunts, there is a grey smudge in the corner of every frame and nobody answers your messages. 📷
Buying used gear is still one of the smartest things a photographer can do. A good body or lens loses much of its value in the first few years and then holds steady, so a careful buyer gets a professional tool for the price of an entry-level one. The catch is that the checks that matter take about twenty minutes and almost nobody does them. Buyers look at the cosmetics, shoot three test frames at the kerb and hand over the money.
This guide gives you eleven checks, in the order you should do them: three before you meet the seller, four on the camera body, three on the lens and one on the deal itself. It works for a private sale in a car park, for a second-hand shop counter and for a marketplace listing that arrives by courier. It is written for all of Europe, so where the law matters we describe the general EU picture and tell you to check your own country's rules rather than pretend one size fits all.
One more thing before we start. The best check in the world is wasted if the gear gets damaged on the way home, or in the bag it lives in afterwards. We come back to that at the end, because a used lens bought at a fair price is also a lens that nobody has insured for you. 🎒
Part 1: Before you meet the seller
The most expensive mistakes in used-gear buying are made at the keyboard, not at the handover. If you do these three things properly, half of the bad listings will filter themselves out before you leave the house.
1. Learn the model's known weak spots first 🧠
Every camera and lens has a personality, and the internet has already catalogued its faults. Some bodies are known for a sticky mirror mechanism after heavy use. Some mirrorless cameras overheat in long video clips, which matters if you shoot video but is not a defect. Some lenses are known for a zoom ring that creeps under its own weight, a focus motor that gets noisy with age, or a rubber grip that goes tacky and peels. Some professional lenses are famous for being excellent but heavy enough to strain the mount of a small body.
Spend thirty minutes on forums, owner groups and the reviews of the exact model. Search for the model name together with words like 'problem', 'issue', 'recall', 'service advisory' and 'common fault'. Manufacturers occasionally issue service notices for specific serial ranges, and a used unit from an affected batch may or may not have been repaired. Write down the three most common faults you find. These become your personal checklist when you hold the camera.
Also work out what a fair price looks like. Look at completed sales, not asking prices: asking prices are wishes, completed sales are facts. Check the price of the same model in good, average and heavily used condition, and note the price of a new unit and of a refurbished one with a dealer warranty. If a camera costs only slightly less than a refurbished one with a guarantee, the guarantee is worth more than the saving. If it costs a third of the market price, assume there is a story and ask for it.
2. Check the serial number and who really owns the gear 🔢
Ask the seller for a clear photo of the serial number on the body and on every lens before you travel. A serious seller sends it in a minute. A seller who refuses, or sends a photo with the number blurred, is telling you something.
Use the number in three ways. First, check that it matches the number engraved on the camera and the one shown in the camera's own menu where the model supports this; a mismatch can mean a swapped body or a repaired unit. Second, compare it with the manufacturer's information on production dates, so that the age of the gear matches the story you are told. Third, ask whether the item was bought new with a receipt in the seller's name. Stolen equipment does appear on marketplaces, and in several countries police and some platforms offer ways to check whether a serial number has been reported. Rules differ, so ask the local police or the platform what is available rather than assuming a lookup exists.
Receipts matter for another reason: they prove the purchase date and sometimes allow the remaining manufacturer warranty to be transferred. Even an old invoice tells you the gear existed in the seller's hands for years, which is reassuring in a way no photo can be.
Finally, ask the seller to clear personal data before you meet. Many cameras store an owner name and copyright text that is written into every file, as well as Wi-Fi network details, Bluetooth pairings and, on newer models, links to a user account. A camera that is still tied to the previous owner's account can be awkward or impossible to set up. Ask the seller to do a full factory reset in front of you and to remove the camera from any app or cloud service. If they cannot do it at the meeting, that is a red flag.
3. Ask for proof, not promises 📋
Send the seller a short list of questions and judge the answers. How old is the camera and how was it used: travel, studio, weddings, sport, wildlife? Has it ever been repaired, serviced or cleaned, and can they show the invoice? Has it been dropped, got wet or spent time in a humid place such as a boat, a tropical trip or a damp cellar? Does it come with the original box, charger, strap, caps and manual? Why are they selling?
Ask for photos that are not the polished ones from the listing: the mount from the front with the lens off, the sensor area with the lens off and the shutter open on a bright day, every corner of the body, the base plate where the screws are, the battery compartment and the contacts. Screw heads with scratched slots mean someone has opened the body. Corrosion in the battery compartment means moisture. A sensor with visible dust in a photo is not a deal breaker, but oily smears are.
Ask for a short video of the camera being switched on, with a few shots fired, the autofocus working and the menu shown. Video is hard to fake and quick to make. A seller who is happy to do all this is probably a seller who has nothing to hide.
Pack for the meeting too. Bring a charged battery of your own, a memory card you can format, a card reader or a laptop, a small torch, a microfibre cloth, a printed checklist and a lens you know well, so that you can test the body with something you trust. A small hard case for the way home completes the kit, and we come back to this in the product section below.
Part 2: The camera body
Meet in daylight, in a place with a table and a power socket – a café, a shop or the seller's home. Do not do this in a car in the dark. Switch the camera on and spend ten unhurried minutes on the body before you look at anything else.
4. Read the shutter count and judge it against the model 🔢
The shutter is the part of a camera that wears out the way brake pads wear out. It is a mechanical part with a rated life, and the number of actuations is the closest thing a camera has to a mileage reading. Many bodies write the count into the metadata of each image, and software tools or the manufacturer's service menu can read it for several models. Others, particularly some mirrorless cameras, do not expose it easily, and electronic shutter operation does not add to the mechanical count. So ask the seller to take a test photo, put it on your laptop and check what a metadata viewer shows for that model.
Treat manufacturer ratings as estimates, not guarantees. As a rough orientation, entry-level bodies are often rated for something like 100,000 to 200,000 actuations, mid-range models higher, and professional bodies for 300,000 or more – but the real rating differs by model, and individual shutters fail well before or well after their rating. A count at half the rating on a body priced as 'barely used' is a negotiation point. A count above the rating on a body priced as a bargain is a fair price for a camera that may need a shutter replacement soon, and you should ask what that repair costs for your model before you decide.
The count should also match the story. A camera sold as 'used on two holidays' with 90,000 actuations is not the camera described. A body with a very low count and a worn-out grip and scratched base was probably carried a lot and fired very little, which is fine. Be suspicious of numbers that are too round, of screenshots rather than live checks and of anything the seller will not repeat in front of you.
Listen to the shutter too. It should sound crisp and even, with no scraping, no hesitation and no slow second 'clack' in the sound. Fire a burst, then a series of single shots at different speeds. Take pictures at the fastest and slowest speeds the camera offers and check that the exposure is even across the frame. A strip of darkness at one side of a fast-shutter image suggests the shutter curtains are not travelling properly.
5. Look at the sensor, the mirror and the stabilisation 🔬
Take off the lens and look into the mount with a torch. On a camera with a mirror, the mirror should be clean, free of scratches and without a lens-fluff halo. On a mirrorless camera, the sensor is visible, and you can do a stronger test: set the aperture to f/16 or f/22, photograph a bright, even surface such as a clear sky or a white wall, defocus the lens a lot and look at the image at 100% on the screen or a laptop. Dust spots show up as dark dots. A few light spots are normal and can be cleaned. Scratches show as lines, and oily marks as smears that follow the same shape in every shot.
Look for a sensor that has been cleaned badly: fine parallel scratches or a hazy corner. Pay attention to the filter in front of the sensor and to any line, mark or unusual colour cast. Take pictures at high ISO with the lens cap on and look for bright hot pixels, then take a long exposure and look for coloured dots. A handful of stuck pixels is common and can often be mapped out in software; dozens are a problem.
If the camera has in-body image stabilisation, switch it on and shake the camera gently – you should hear a faint, soft hum or feel a light movement when the sensor floats, and you should hear no rattle when it is switched off. A rattle from a sensor that should be locked is a sign that the system has been damaged by a drop. If the camera has a flip screen, a fully articulating screen or a tilting one, open and close it ten times and look at the cable and hinge for wear.
6. Test every button, dial, port and seal 🎛️
Touch everything. Press every button and turn every dial, in both directions, for several clicks. They should click clearly, move smoothly and respond on the screen every time. Check the mode dial, the rear dial, the joystick and the back button. Worn contacts show up as buttons that sometimes do not register. Test the touchscreen across the whole surface, in the corners too, because a dead zone is expensive to fix.
Open every door: the card slots, the battery compartment, the port covers. The rubber seals around them keep out dust and rain and are one of the first things to age. Look for tears, flattening and a missing flap. Insert a card, format it in the camera and write a burst of images to check the card slots work. If there are two slots, test both. Plug in a cable or a microphone to test the ports, and fit a flash to check the hot shoe.
Examine the body for dents. A dented corner or a bent frame is an obvious sign of a hard fall, and a hard fall can misalign the mount or the sensor even when the camera still works. Look at the lens mount: it should be free of grooves, with an even shine and no bright metal-on-metal wear around the bayonet. Heavy wear on the mount is typical of a body that was used with heavy lenses or changed lenses constantly, and a loose mount shows as a lens that wobbles slightly after it is locked on. Put a lens on, lock it and try to move it gently. There should be no play at all.
Check the viewfinder and the screens for dead pixels, burn-in and scratches. Look through the viewfinder and shake the camera lightly to listen for loose parts. Check the strap lugs and the tripod socket, where cheap mounting plates or overtightened screws leave damage. A stripped tripod thread on a body that is sold as 'used only on holiday' is worth a question.
7. Check the battery and the firmware 🔋
Lithium-ion batteries age whatever you do. Many cameras show a battery health or number-of-charges indicator in the menu. If yours does, write it down. A battery that is already at 60 or 70 percent of its original health will give you a short day, and replacement batteries are a cost to add to the price. Genuine spare batteries are not cheap, and cheap unbranded ones are a gamble on both capacity and safety.
Look at the physical battery: a swollen, warped or leaking battery should not be used and should not be carried on an aircraft. Check the contacts on the camera and on the battery for corrosion or green deposits, a sign that it has been stored damp. If the seller has several batteries, ask for each one's age. Finally, check the firmware. Look in the menu for the current version and compare it with the version the manufacturer lists; old firmware can often be updated, and a camera that cannot be updated or shows a strange version needs another look.
As a last check, run the camera for a while. Record a few minutes of video, take a few hundred shots in a burst and watch for overheating warnings, freezing menus and sudden restarts. Intermittent faults are the worst kind because they vanish in a five-minute test, so give the camera some real work before you pay.
Part 3: The lens
Lenses are where used-gear buying gets truly rewarding, because glass ages far better than electronics. A well-kept lens from a decade ago can still be as sharp as a new one. It is also where the most expensive hidden problems live, because a lens can look perfect on the outside and be unusable inside.
8. Inspect the glass for fungus, haze, scratches and separation 🔍
Take the lens off the camera, remove both caps and hold it up to a bright window or a torch. Look through it from both ends, tilting it slowly so that the light passes through every element. You are hunting for four things. Fungus appears as fine branching threads or cobweb patterns, and it grows when a lens is stored in humid, dark conditions. Haze is a milky veil caused by oil vapours from internal lubricants or by age, and it lowers contrast. Scratches on the front element are visible at an angle, and small ones usually do little to the image; a coating that has worn off in patches does more. Separation shows as rainbow-coloured edges or a milky ring around the rim of a cemented element, and it means the glue between lens elements is failing.
Fungus is the most serious of these because it can spread, and removing it requires a specialist to open the lens, which is often more expensive than the lens is worth. If you want to understand how it starts and how to keep your own lenses safe afterwards, our guide to how humidity destroys camera lenses explains the mechanism and the storage routine.
Look at the rear element and the area near the mount too. Check that the front thread is not dented, that any filter threads are clean, and that the hood fits. Press a finger lightly on the front element and move it; it should not wobble. Look for small dust particles inside: a few are normal on an older zoom, because zooming pumps air in and out, but a heavy layer of dust or visible oil on the diaphragm blades is not.
A practical note about 'cleaning marks': lenses that have been wiped with the wrong cloth have fine circular swirls. Hold the lens at an angle against a lamp and you will see them. They matter more on dark, back-lit scenes, where they can cause flare.
9. Test the mechanics: autofocus, stabilisation, aperture and rings ⚙️
Put the lens on a body you trust and work through every function. Turn the focus ring from end to end: it should be smooth, with no gritty spots, and the focus motor should not make grinding noises. Run the autofocus from near to far several times and in low light, and watch for hunting, hesitation and loud buzzing. Switch between autofocus and manual focus. Test the focus-limiter switch if there is one.
On a zoom lens, run the ring through the full range slowly and quickly. It should have even resistance. Point the lens down and then up, and check for zoom creep, where the barrel slides out under its own weight. Extend the zoom and look for any play or a wobble between the barrels, which indicates worn guides. Listen for rattling. If the lens has an optical stabiliser, switch it on and listen for the soft click or hum; a rattle with stabilisation switched off is normal on some designs, but a rattle at all other times can mean a loose group.
Look into the lens from the rear while changing the aperture. The blades should move smoothly and snap back without hesitation, and they should be dry. Oily blades are slow, can stick at small apertures and affect exposure consistency. If the lens has an aperture ring, test every click. Check the electrical contacts on the mount for dirt or wear, and test every switch on the barrel. Finally, check any weather seal on the mount: a missing gasket on a lens sold as 'weather-sealed' is a missing feature.
10. Shoot a quick sharpness and focus test 🎯
This is the check that finds the faults you cannot see. A lens can have clean glass and still be misaligned inside from a knock. Mount it and photograph a flat, detailed target, such as a page of printed text or a brick wall, at the widest aperture, at a middle aperture and at a small aperture. Open the images at 100% on a laptop and compare the four corners with the centre. Some softness at the widest aperture is normal, particularly in the corners of fast lenses. But if one side is clearly softer than the other, the lens is probably decentred, which usually means a knock or a failed repair.
Test the focus accuracy. Place a target on a table at an angle, focus on a mark in the middle and check whether the sharpest point is exactly where you aimed. Front focus and back focus show up as a systematic miss in one direction. Many modern bodies can calibrate a lens, so a small miss may be fixed in the menu, but a lens that misses by different amounts each time is a mechanical problem. Test it at both ends of the zoom range and at close and far distances.
Finally, shoot a few frames into a bright light source and look for flare, ghosting and loss of contrast, because worn or damaged coatings show up there first. If you are buying a long telephoto lens, test it while hand-holding it with the stabiliser on and off, because a malfunctioning stabiliser can make images worse rather than better. For a longer view of how telephoto lenses get damaged before they ever reach a second-hand shelf, see our guide to the transport mistakes that kill telephoto lenses.
Part 4: The deal
11. Understand the warranty, the return rights and how to pay 💶
Everything above can be perfect and you can still lose money if the deal is wrong. The legal protection you have depends on who sells to you, so find out before you pay.
When you buy from a business in the EU, you are a consumer and consumer rules apply. In general the EU legal guarantee for goods lasts two years, and for second-hand goods the seller and buyer may agree a shorter period, but not less than one year, provided the buyer is told clearly and unambiguously when the contract is concluded. Member States apply these rules in their own way, so check the exact wording where you live and make sure the shorter period, if there is one, is written on the receipt. If you buy at a distance from a business, such as online, you normally also have a right to withdraw within 14 days of receiving the goods. That is a real safety net: use it to run the checks above as soon as the parcel arrives.
When you buy from a private person, consumer protection normally does not apply in the same way. Sales are often 'as seen', and your options after the handover are limited. That is why the checks in this guide matter most in a private sale. Ask the seller to write a short bill of sale that lists the item, serial numbers, price, date and the condition as described, and have both of you sign it. It costs nothing and it matters if the description turns out to be false.
Pay in a way that matches the risk. For a face-to-face sale, cash in a public place is normal, but check what you are carrying and meet where there are other people and cameras. For a distance sale, use a payment method with buyer protection and avoid bank transfers to people you do not know. Be wary of anyone who asks you to pay outside the platform's protection, or to hurry because 'another buyer is coming'. Watch for sellers who are not in the country they say they are in, and for prices that are far below any completed sale.
Finally, ask for everything that belongs in the box: the charger, the caps, the strap, the body cap, the original box and the manual. Missing accessories are not a reason to walk away, but they are a reason to lower the price, because replacing a charger and a battery can cost real money. Keep the receipt, the serial numbers and the photos of the checks in a folder. If you ever sell the gear on, that folder adds value.
📦 Small hard cases for the handover: body, lens, cards and batteries
Part 5: Getting it home, and keeping it safe
You paid a fair price for a good body and a clean lens. The next risk is not the previous owner but you. The most common damage to second-hand gear happens in the first week, on the way home and in the bag that was bought for a different kit. A lens dropped from table height on a hard floor can lose its alignment, and a body knocked in a rucksack can lose a corner.
Think about the journey in two parts. For the walk or drive home, a small hard case with a foam or divider system is a good idea, because it holds the gear still and protects against knocks, rain and spills. For the long run, think about the way you will use the gear: a body and two lenses for weekend trips fits a different case than a full kit that flies in the cabin. Our guide to the camera hard case walks through sizes and layouts, and the article on case, bag or backpack will help if you are not sure which format suits you.
If you plan to travel with the gear, plan the carry-on early. A wheeled or compact carry-on case with a divider kit keeps a mirrorless system together, protected and legal for the cabin. We describe how professionals pack in how to pack camera gear for three weeks in one carry-on, and which cases suit common bodies in which Peli case for a Sony A7 IV or Canon R5 with three lenses. For a broader overview of setups for different types of shoots, see the best camera cases for photographers in 2026.
Finally, think about the places the camera will go. Sand, dust and spray affect used gear more than new, because worn seals protect less. Read our 11 rules for shooting in dust and sand before the first beach trip.

Frequently asked questions
Is it safe to buy a used camera online?
It can be, if you buy from a business that gives you a written warranty and a return period, or from a platform that offers buyer protection. In a distance sale from a business you normally have a 14-day right to withdraw in the EU, so run every check in this guide as soon as the parcel arrives. Be careful with private sellers who want payment outside the platform.
What shutter count is too high?
There is no single number. Compare the count with the rated life for the exact model and with the price. A body at a quarter of its rating is a good buy; a body at or beyond its rating should be priced as if the shutter needs replacing, which is a repair you should ask about before you buy.
Can fungus in a lens be removed?
Sometimes, by a specialist who opens the lens and cleans the elements, but the cost can be high and the coatings may be damaged. For most buyers the sensible choice is to walk away from a lens with active fungus unless the price reflects a service.
Should I buy a used lens or a used body first?
Lenses hold their value and their quality for much longer than bodies, so a good used lens is usually the better long-term investment. Bodies change fast and lose value faster, which is why a slightly older body paired with a very good lens is a common smart choice.
How should I carry a used camera home?
In a padded or hard case that holds the gear still. A compact hard case with foam or dividers protects against knocks and rain on the journey, and it can serve as the permanent home for the kit afterwards.
The short version
A used camera or lens is a great deal when you know what you are checking. Do your homework on the model, confirm the serial number and the paperwork, test the shutter, the sensor, the controls and the battery, look through every lens with a torch, run a sharpness and focus test, and make sure you understand the warranty before you pay. Then get the gear home in something that will protect it, because your careful checks only matter if the lens arrives the way it left the seller's hands. 📷
