Used Camera Lens on eBay: Fungus, Haze, and Mount Checks
A used camera lens can be a better upgrade than a new camera body, but the listing has to prove the glass and mechanics. The expensive surprises are fungus, haze, scratches, oil on aperture blades, loose zoom rings, damaged filter threads, mount wear, and sample photos that do not come from the actual lens.
Quick read
What changes the decision
- Ask for front and rear glass photos under a bright light, plus photos through the lens that show fungus, haze, coating marks, dust, scratches, or balsam separation.
- Confirm aperture blades are clean and snappy, autofocus or manual focus works, zoom rings do not grind or creep, the mount is not bent, and filter threads are not dented.
- Price the lens after caps, hood, case, sample photos, return terms, cleaning risk, and whether the mount actually fits the camera system you plan to use.
