Description
The Canon EF 16-35mm f/2.8L III improves outer and corner sharpness over its predecessor with a new optical formula and modern coatings, holding a fast, constant f/2.8 aperture across the range.
Optics
New aspherical elements minimise distortion, and Ultra-Low Dispersion glass controls chromatic aberration, delivering professional-grade image quality across the full-frame wide-angle range.
Handling
A ring-type USM with a high-speed CPU and optimised algorithms gives fast, accurate autofocus, with internal focusing and full-time manual override. A 9-blade rounded aperture gives smooth bokeh. Dust- and water-resistant sealing throughout, with a fluorine coating on the front and rear elements for easier cleaning.
