Offered here with a Canon RF-mount, this lens provides a versatile full-frame equivalent zoom range of 29-80 and a wide constant aperture of f/2.8 throughout the entire zoom range. The lens design includes three high-precision glass-molded aspherical elements coupled with a special low dispersion element. Together they minimize the total number of elements for superb optical quality without excessive weight. Autofocus is exceptionally fast and quiet thanks to the lens's stepping motor, which can be particularly useful when shooting video or fast-moving subjects such as children and animals. An ultimate workhorse, the lens features a minimum focusing distance of just 4.8", enabling it to be used for macro-style close-up photography, and the lens is also outfitted with a rounded seven-blade diaphragm for a pleasing bokeh quality.
