Canon 16-35mm f/2.8L EF II Wide-Angle USM

The ultra-wide angle EF16-35mm f/2.8L USM was developed to succeed the EF16-35mm f/2.8L USM lens released in 1995. Though the previous model received high praise from professional users, the recent proliferation of digital cameras, which have smaller image sizes than regular 35mm cameras, created a necessity for wide-angle lenses with an even shorter focal length. 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.
