Canon EF 16-35mm f/2.8L III USM 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.
Both SWC and ASC coatings have also been applied to the elements in order to reduce lens flare and ghosting for increased contrast and color accuracy.
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.
