Camera gear holds value and ages well. A two- or three-year-old body or lens often performs almost identically to the current model for a fraction of the price, and most of the things that go wrong are easy to spot if you know where to look. The savings are real, but used buying rewards a careful eye and punishes a rushed one. This guide is how to be the careful buyer.
If you are still deciding what to buy in the first place, our what camera should you buy guide frames the decision, and the exposure triangle covers the fundamentals every used body and lens will put in your hands.
Why buy used
The case for used is simple: cameras and lenses depreciate quickly in the first year or two, then level off. Someone else absorbs that first drop, and you get gear that is nearly current for much less. Lenses in particular barely change year to year, so a well-kept lens from several years ago is often identical in image quality to a new one. The same money buys you a better body, faster glass, or both, used instead of new.
The risk is that you cannot see how a previous owner treated the gear. A camera that was babied looks and works like new; one that lived on a beach or in a damp closet can hide problems. The rest of this guide is about telling those two apart before your money leaves your hands.
How to inspect a used camera body
Start with the shutter count, the closest thing to a camera's odometer. Every mechanical shutter is rated for a number of actuations, often in the low hundreds of thousands on enthusiast and pro bodies. A count well under the rating means plenty of life left; a count near or over it is a real risk. You can read the count from a recent file's metadata using free online tools, or ask the seller for a screenshot. A camera with a suspiciously low count on a heavily worn body is a flag the count may be wrong. Note that mirrorless cameras with electronic shutters may show low mechanical counts but still have heavy use, so weigh it alongside cosmetic wear.
Then check the sensor. Set a small aperture like f/16, point at a plain bright surface, and take a photo, then zoom in: a few specks of dust are normal and cleanable, but scratches or marks that do not move are sensor damage you cannot fix cheaply. Inspect the body for dents and cracks that suggest a hard drop, look at the lens mount for wear, and check the screen and viewfinder for cracks or dead pixels.
Last, test everything that moves or connects. Work every dial, button, and switch. Mount a lens and confirm autofocus and metering work. Open every door and try every port: the card slots, the battery door, the HDMI and USB and microphone jacks. Fire the shutter at a range of speeds. Check the battery holds a charge and ask how many batteries and chargers come with it. A body that passes all of this is very likely a good buy.
How to inspect a used lens
For a lens, the glass is everything. Hold it up to a bright light and look through it from both ends for fungus, which looks like fine white webbing or spots and can spread and etch the coatings; fungus is a reason to walk away. Look for haze, a milky internal cloudiness that softens images, and for separation, a rainbow or oily look where cemented elements have come apart. Surface dust inside a zoom is normal and rarely affects images; internal damage is the concern.
Then check the front and rear elements for scratches and coating wear under angled light. Light cleaning marks are usually harmless; deep scratches over the center can show in your photos. Look for oil on the aperture blades, which can make the aperture sluggish, and check that the blades open and close cleanly.
Last, test the mechanics. Turn the focus ring and the zoom ring through their full range; they should move smoothly without grinding or excessive play. Mount the lens and confirm autofocus drives quickly and locks, and that image stabilization, if it has it, kicks in without odd noises. Check the mount for wear and the filter threads for dents that would stop a filter screwing on. A lens with clean glass and smooth mechanics is often as good as new.
Where to buy used
Where you buy changes how much protection you get. Reputable used dealers, the specialist camera resellers and the used departments of major retailers, inspect, grade, and warranty their gear. You pay a little more than a private sale, but you get a return window and a warranty, which is worth a lot on an expensive body. This is the safest route, especially for your first used purchase or anything pricey.
Private sales, through classifieds and marketplace apps, are cheapest and riskiest. There is no warranty and little recourse, so the inspection above matters most here. Meet in person when you can, run through every check, and use buyer-protected payment rather than cash or irreversible transfers. Online auction and marketplace platforms sit in between: read the seller's feedback, favor detailed listings with real photos of the actual item, and lean on the platform's buyer protection.
Across all of them, a price that is far below the going rate is a warning, not a bargain. It usually means a hidden problem, a scam, or stolen gear. Check the typical used price first so you know what is reasonable, and be ready to walk away from a deal that feels off.
Common mistakes
The most common one is skipping the inspection because the price looks great and the seller seems nice, then discovering fungus or a worn-out shutter at home. The checks take minutes and save real money. The second is ignoring shutter count on a body that otherwise looks clean; a low price on a camera near its actuation rating is not a deal. The third is paying with an irreversible method on a private sale, which removes your only recourse if the gear is not as described. The fourth is chasing the cheapest listing anywhere; the safest used buy is often a dealer with a warranty, not the lowest number you can find.

What is a safe shutter count to buy?
It depends on the camera's rating, which is often in the low hundreds of thousands of actuations for enthusiast and pro bodies, lower for entry-level ones. A count well under the rating leaves plenty of life; a count near or over it is a real risk and should be reflected in a much lower price. Read the count from a recent file's metadata or ask the seller for a screenshot, and weigh it against how worn the body looks.
How do I check a used lens for fungus?
Hold the lens up to a bright light and look through it from both ends. Fungus appears as fine white webbing, branching threads, or spots inside the glass. It can spread and etch the lens coatings over time, so it is a reason to walk away rather than negotiate. Surface dust is normal and harmless; internal fungus, haze, or element separation are the real concerns.
Is it safer to buy used from a dealer or a private seller?
A reputable used dealer is safer because the gear is inspected, graded, and usually comes with a return window and a warranty, which matters most on expensive bodies. Private sales are cheaper but carry no protection, so your own inspection has to be thorough and you should use a buyer-protected payment method. For a first used purchase or anything pricey, a dealer is the safer route.
