Why buying used makes sense for macro lenses
I bought my first proper macro lens secondhand on Facebook Marketplace, and it was one of the better gear decisions I have made. Macro lenses tend to hold their optical quality well over time. Unlike camera bodies, which become outdated as sensor technology improves, a well-made lens from ten years ago is just as sharp today as the day it was made. The main risks with used lenses are mechanical and cosmetic, not optical obsolescence, and most of those risks are manageable if you know what to look for.
The savings can also be significant. A lens that retails new for $800 might be found used in excellent condition for $400 to $500. For a macro lens specifically, which you are likely to keep for many years, that kind of saving is worth the extra care involved in buying secondhand. If you are still figuring out which lens to get in the first place, check out my article on macro lenses for mushroom photography first.
Where to buy
Not all secondhand sources are equal, and where you buy affects both the price you pay and the protection you have if something turns out to be wrong.
Dedicated used camera dealers
Sites like MPB, KEH, and Adorama Used are the safest option. They grade lenses carefully, describe condition accurately, and offer return policies. You will pay slightly more than you would on a private sale, but the peace of mind is worth it, especially for more expensive lenses. Their condition ratings (Excellent, Very Good, Good, etc.) are generally reliable guides to what you are getting.
eBay
A huge selection at competitive prices, but quality varies enormously between sellers. Stick to sellers with strong feedback scores and check that they offer returns. Read the listing description carefully rather than relying on the photos alone, and do not hesitate to message the seller with questions. The eBay buyer protection policy does provide recourse if the item is not as described.
Facebook Marketplace and local sales
The best prices are usually found here, but also the most risk. There is no buyer protection, no returns, and no recourse if the lens turns out to have problems you did not spot at the time. This is where knowing exactly what to inspect before handing over money really matters. Always meet in a public place and bring your camera body to test the lens properly before buying.
What to check before you meet the seller
Before you even arrange to meet or commit to a purchase, there are a few things worth doing remotely.
First, check the lens model carefully. Lens naming conventions can be confusing, especially for Nikon, where the difference between a D-type and a G-type or AF-S lens has real implications for autofocus compatibility on different bodies. Make sure the specific version you are looking at is actually compatible with your camera. If you are also in the process of choosing a camera body, my guide to cameras with focus stacking capability covers what to look for there. If in doubt, look up compatibility before you go.
Second, research the typical price for that lens in that condition. Completed eBay listings are a good reference for realistic market prices. If the asking price is significantly below market rate, it is worth asking why. Sometimes it is a motivated seller who just wants it gone. Sometimes there is something wrong with it that the listing does not mention.
Third, ask the seller directly how the lens was used and stored. A macro lens that spent years shooting studio products on a tripod has had a very different life than one that went on outdoor shoots in wet conditions. You will not always get a straight answer, but the question is worth asking.
Inspecting the glass
This is the most important part of the inspection. The optical elements are what form the image, and problems here are the hardest and most expensive to fix. You need good light for this, ideally a bright torch or a phone torch held at an angle to the lens.
Fungus
This is the thing to watch for most carefully. Lens fungus grows inside the barrel when a lens is stored in damp, dark conditions over a long period. It appears as a hazy, web-like or branching pattern inside the glass when you look through the lens with light behind it. Even a small amount of fungus will reduce contrast and sharpness. A significant amount can destroy the lens optically. Fungus can also spread to other lenses stored nearby. If you see any sign of it, do not buy the lens.
Scratches
Inspect the front and rear elements for scratches. Small, fine scratches on the front element (not on the rear) will often have minimal effect on image quality in practice, since they are far from the focal plane. But deep scratches or scratches on the rear element are more serious and should be reflected significantly in the price if the seller is being fair. Scratches in the coating rather than the glass itself are less of a concern.
Haze and separation
Haze is a general cloudiness inside the lens, different from fungus in that it has no visible structure. It reduces contrast across the image. It can be caused by old lubricants evaporating onto the glass elements, by cleaning with the wrong products, or by general age. Look through the lens at a bright light source and check for any cloudiness.
Separation is when the optical cement bonding two lens elements together starts to fail. It usually appears as an iridescent ring or pattern at the edge of an element. It is uncommon but worth checking for, particularly in older lenses.
Dust
Some dust inside a lens is normal and virtually inevitable in any lens that has been used. A small amount has essentially no effect on image quality. Do not let a seller charge full price for a dusty lens, but do not walk away from one just because it has a few specs inside either. Heavy dust that is clearly visible in images is a different matter.
Checking the mechanics
Focus ring
Turn the manual focus ring through its full range, from minimum focus distance to infinity. It should move smoothly and evenly with consistent resistance throughout. Stiff spots, grinding, or a gritty feeling can indicate old lubricant, internal damage, or sand and debris inside the barrel. A very loose, sloppy focus ring with no resistance can mean the helicoid is worn.
Aperture blades
Set the lens to its widest aperture and look at the blades from the front. They should open fully and cleanly. Then stop down a few stops and check that the blades form a clean, even polygon without any blades sticking or moving unevenly. Oily aperture blades are a common issue on older lenses. You can often spot them by a slight sheen or oily residue on the blade surfaces. An oily aperture causes the blades to move sluggishly and can mean the aperture does not close to the set value reliably.
Zoom ring (if applicable)
Most dedicated macro lenses are primes, so this is less relevant. But if you are looking at a zoom with macro capability, check that the zoom ring moves smoothly and that the lens does not creep (slowly extending or retracting under gravity when pointed up or down).
Physical condition of the barrel
Some wear marks and small scuffs on the exterior are normal for a used lens and purely cosmetic. But look for signs of impact damage: dents in the barrel, a filter thread that is not perfectly round, or a zoom or focus ring that feels like it was knocked out of alignment. A lens that has been dropped hard may have internal misalignment even if the exterior looks mostly fine.
Testing autofocus and electronic communication
Bring your camera body to the inspection. There is no substitute for actually mounting the lens and confirming everything works before you hand over money.
Mount the lens and confirm the camera recognises it. Most modern cameras will display lens information in the EXIF data or on-screen. If the camera shows no lens information or throws an error, there is a communication problem between the lens and body.
Activate autofocus and test it on a subject with clear contrast, like a printed page or a pattern on your phone screen. The AF should acquire focus quickly and without hunting excessively. Listen for any grinding or unusual sounds from the focus motor. Test both single shot and continuous AF if your camera supports it. Also check that the lens will focus at macro distances specifically, not just at normal shooting distances. This is particularly relevant if you are buying for an Olympus body where autofocus is needed for in-camera focus bracketing. If you are new to that system, my article on what Micro Four Thirds is explains how all of this fits together.
If the lens has image stabilisation, activate it and listen for the stabilisation system engaging. You should hear a faint hum and see the viewfinder image stabilise when you half-press the shutter. A stabilisation system that makes no sound or produces a loud rattling is worth querying.
Testing at macro distances
This step is specifically important for macro lenses and is often skipped, which is a mistake. Some lenses perform well at normal distances but reveal problems only at close range: soft corners, front or back focus issues, or aberrations that are much more visible at 1:1 magnification.
Get as close as the lens will allow and take a test shot of something with fine detail, ideally flat (a printed page works well) so you can check corner-to-corner sharpness. Check the image on the camera screen at 100% zoom. The centre should be sharp. The corners should be reasonably sharp. If the image is clearly soft even in the centre at minimum focus distance, or if focus seems to land in front of or behind where you expected, that is a red flag worth investigating.
When to walk away
Some issues are deal-breakers and some are just negotiating points. Here is a rough guide.
Walk away if you see any fungus inside the lens. It is not worth it regardless of price. Walk away if there is obvious element separation. Walk away if the autofocus does not communicate with your body at all. Walk away if the aperture blades are heavily oiled and sticking. These are all problems that are expensive to fix and will affect your images.
Consider negotiating rather than walking away if there are minor scratches on the front element that do not affect visible image quality. Minor dust that is not visible in images is also negotiating territory rather than a reason to leave. Some front element coating wear that the seller has disclosed honestly is also manageable, depending on how severe it is and how much they are asking.
Negotiating the price
If you find issues during the inspection, you have every right to negotiate. Most sellers expect some back and forth, particularly on private sales. Be specific about what you found rather than just saying it is not in great condition. Pointing to a specific scratch or a slightly stiff focus ring and explaining the concern is more persuasive than a vague objection.
Know your walk-away price before you go in. It is easy to get caught up in the moment and pay more than you intended, especially if you have already driven to meet the seller. Having a clear number in your head before you go helps.
And finally, if something does not feel right about the lens or the seller, trust that instinct. There are always more lenses on the secondhand market. A bad purchase at a good price is still a bad purchase.
Best of luck out there.
