Canon EF 28–300mm f/3.5–5.6L IS USM is an all-in-one professional zoom covering a massive focal range, ideal when lens changes are impractical. On APS-C cameras it offers a 45–480mm equivalent range. Built-in IS allows shooting at shutter speeds about three stops slower, with Mode 2 detecting intentional panning and tripod detection for stability. Ring-type USM ensures fast, quiet autofocus. Zoom tension can be adjusted and locked. The optical design includes 23 elements with UD and aspherical lenses to maintain high resolution throughout the range. An EMD diaphragm with a rounded aperture produces attractive background blur. Included: Canon EF 28–300mm f/3.5–5.6L IS USM lens, front and rear caps, hood, UV filter, tripod collar, pouch.
