Selling a used camera lens online can be a great way to earn extra money, but getting the best possible price requires some preparation and strategy. Start by cleaning your lens thoroughly, including the glass, body, and mount, to make it look as close to new as possible. Next, inspect it for any scratches, fungus, or dust, and mention these details honestly in your listing—transparency builds trust. Take high-quality, well-lit photos from multiple angles, showing both the lens and accessories such as caps, hood, or case. 

Research current market prices on platforms like Camerasellonline, Sellyourgadget, eBay, MPB, or KEH to determine a realistic and competitive price. When writing your description, include details like the brand, focal length, aperture, and compatibility, and highlight any special features or unique qualities. Finally, choose a reliable marketplace, offer secure shipping, and communicate promptly with buyers. A clean presentation, honest description, and fair price can help you sell your lens faster and for maximum value.
