Canon 70-300mm f/4

{"overview":"The Canon EF 70-300mm f\/4-5.6 IS USM is a consumer-grade telephoto zoom for EF-mount Canon SLR and DSLR bodies, offering a variable maximum aperture across its 70–300mm range. These are wholesale hammer results rather than retail asking prices, and the lens typically sells for noticeably more through dealers and online marketplaces.","buying_guide":"Check the front and rear elements for fungus, haze and cleaning marks, and look through the zoom range for signs of internal dust or lens separation at element edges. Exercise the aperture blades to confirm they are dry and snappy, rotate focus and zoom rings for smooth travel without grinding, and — crucially on this model — listen and feel for the IS unit engaging quietly when the shutter is half-pressed, as a rattling or noisy stabiliser is a known weakness.
