Selling my Canon EF 100–300mm f/4.5–5.6 Ultrasonic (USM) lens for Canon EOS cameras. This is a full-frame EF-mount telephoto zoom, ideal for wildlife, sports, or general telephoto photography. The lens is in clean and fully working condition, with smooth zoom/focus action and clear optics. Autofocus is fast and quiet thanks to the Ultrasonic Motor (USM). Details: • EF mount – compatible with all Canon EOS film and digital SLRs • Clean optics – no fungus, haze, or major marks • Fast, quiet autofocus with USM • Original Canon box included (box shows some wear) A great affordable telephoto option with solid image quality
