A macro len is a necessity when it comes to taking pictures up close. A very reputable seller on eBay is selling the highly popular Canon EF 100mm f/2.8 Macro USM BOXED in Mint Condition. The auction features a lightly used Canon EF 100mm Macro USM lens in perfect working condition in original box with instructions, both caps and a third party rubber lens hood in excellent shape too. Glass pristine inside out, blades free and clean, focus smooth as it should be. Only drawback: a few dust particules inside the lens that won’t affect the performance.
