A lens is often worth more than people expect, and it is judged on different things from a camera body. The body's grade is mostly about the outside and whether it works. A lens is judged on its glass and its mechanics, and some of the problems that matter most are invisible until you know where to look.
This guide is a home check you can do in ten minutes with a phone torch and your camera. It will not turn you into a repair technician, and it does not need to. It will tell you what to describe honestly when you ask for a price, so there are no surprises when the lens is checked.
Fungus grows inside lenses stored in warm, humid places, which describes a lot of Indian cupboards in the monsoon. It looks like fine threads, a spider web or a small fuzzy star on or between the glass elements.
How to check: take the lens off the camera, take both caps off, and shine the torch through the rear of the lens while you look through the front. Tilt it slowly. Then do it the other way round. Fungus shows up clearly against the light in a way it never does in a bright room.
Haze is a milky or foggy look across an element, as if someone breathed on the glass from inside. It lowers contrast in photos, especially against the light.
How to check: use the same torch test. A clean lens looks clear and dark around the light; a hazy one glows grey across the whole element.
Look at the front and rear glass at an angle under a normal light. Fine cleaning marks, deeper scratches and chips at the edge of the glass are all worth noting. A scratch on the rear element is usually more visible in photos than one on the front.
If a filter has been screwed on the front for years, remove it and check the glass underneath too.
A few specks of dust inside a lens are common, even on lenses that have been well looked after, because zoom lenses move air in and out. Note it, but do not panic about it. Heavy dust that looks like a sprinkling of sand is a different matter and worth mentioning.
Look into the front of the lens while changing the aperture on the camera and taking a photo. The blades should move quickly and form a clean shape. Oil on the blades shows as a shiny, wet look; sticky blades are slow to close.
Mount the lens, set the lens and camera to autofocus, and focus on something close, then something far away, a few times. Focus should lock without hunting endlessly, and there should be no grinding or clicking. If the lens has a manual focus ring, turn it: it should feel even all the way round.
If the lens has stabilisation (often marked IS, VR or OSS), switch it on, half-press the shutter and look through the viewfinder or at the screen. The image should settle. A loud rattle or a jumping image is a problem.
Turn the zoom ring from end to end. It should be smooth, not gritty or stiff in one place. Point the lens down: if the zoom slides out on its own, that is zoom creep, common on older telephoto zooms.
Look at the metal mount at the back for worn or bent parts, and check that the gold contacts are clean. Wipe dirty contacts gently with a dry cloth.
Front and rear caps protect the glass in transit and are the first thing a buyer asks about. Find the hood if the lens came with one, and the box if you still have it.
A lens is always its own line, separate from the camera body, because a body and a lens lose value at different rates. Our lens list currently has 168 priced lenses: Canon 66, Nikon 46, Sony 32, Panasonic Lumix 11, Fujifilm 10, Tamron 2 and Sigma 1. You can price a lens on its own at sell camera lens, or add it on the step after you choose the body.
The lens people sell most often is the kit lens. On the Canon EOS 1500D page, for example, 31 of 36 price requests since May 2026 that named a lens named the EF-S 18-55mm; on the Sony A7 III page, 15 of 20 named the FE 28-70mm.
At pickup, our agent photographs the sensor and mount with the lens removed, and checks the camera powering on and firing the shutter. If what you described matches what the agent finds, the price stands. If something material is different, the agent re-quotes with the reason. Pickup covers lenses in every city we serve, including Delhi, Mumbai, Bangalore and Pune. Anywhere else in India, a lens can be sold by courier after a video call check; cap both ends and wrap it separately.
We do not buy dead cameras. We do buy working lenses from them, on their own. This is one of the most common reasons people end up on the lens page.
We would not recommend opening a lens at home. Describe what you see honestly instead, and let the lens be checked.
Some are on our priced list. For any lens that is not listed, call or WhatsApp +91 95608 22859 and we will tell you whether we buy it.
No. The camera price is for the body only. The kit lens is quoted as its own line.
Yes. Each lens is a separate item, and you can sell it without the body.
