Canon 75-300mm f/4.5-5.6

{"overview":"The Canon EF 75-300mm f\/4.5-5.6 III USM is an autofocus telephoto zoom for Canon's EF mount, fitting full-frame and APS-C EOS bodies. With just one data point, the typical price range cannot be reliably bracketed, but values consistent with that result are what the lens currently sells for in the auction market in 2026. Cosmetically tidy examples with smooth zoom and focus action tend to fetch the upper end, while hazy or fungused copies sell for considerably less.","buying_guide":"Inspect the front and rear elements for fungus, haze and coating scratches, as budget telezooms of this era are often stored poorly and develop internal contamination. Check that the USM autofocus engages quickly and quietly, that manual focus is not stiff, and that the zoom action is smooth without excessive creep.
