In response, the new EF16-35mm f/2.8L USM achieves a shortened focal length of 16mm, producing the widest-angle range in its class and allowing users of digital AF SLR cameras to achieve the ultra-wide zoom ranges of conventional cameras.

The rugged physical characteristics of the unit also suit it to professional use in harsh environments, with the lens mount, switch panel, zoom ring and focusing ring outfitted for water- and dust-resistance, ensuring exceptional reliability under even the most grueling conditions.
