Canon EF 16-35mm f/2.8L III USM

The EF 16-35mm f/2.8L III USM from Canon is a workhorse wide-angle zoom and member of the well-regarded L-series of lenses. Featuring a series of specialized elements, this lens utilizes a trio of aspherical elements and two ultra-low dispersion glass elements to control a variety of aberrations for high sharpness and clarity. Complementing its optical prowess, a ring-type Ultrasonic Motor offers fast, smooth, and near-silent autofocus performance, which is further benefitted by full-time manual focus operation and an internal focusing design. The lens is both water and dust-resistant, and fluorine coatings have also been applied to the front and rear elements to protect against fingerprints and smudges from affecting image quality. Constant f/2.8 maximum aperture offers consistent performance and excellent light transmission throughout the zoom range. Two ultra-low dispersion elements are used to minimize chromatic aberrations as well as eliminate color blurring around the edges of subjects. As a member of the esteemed L-series, this lens is sealed against dust and moisture for working in inclement environmental conditions.
