Canon EF 28-200mm f/3.5-5.6 USM - Canon EF Mount

The Canon EF 28-200mm f/3.5-5.6 USM is a versatile 'superzoom' designed for full-frame and APS-C EF mount cameras. It utilizes an Ultrasonic Motor (USM) for fast and quiet autofocus, making it a convenient travel lens that covers everything from wide-angle to telephoto. The optical design includes aspherical elements to maintain image quality across the broad zoom range while keeping the lens relatively compact. On the used market, these lenses can suffer from 'zoom creep' where the barrel extends under its own weight; check the tightness of the zoom mechanism. The AF/MF switch should be tested for positive engagement. SDS checks the internal ribbon cables, which can occasionally wear in high-ratio zooms, and ensures the autofocus remains accurate at both the 28mm and 200mm positions.
