About half the price of the 16-35 f/2.8 lens, this L-series lens has an entirely new optical design with three Aspherical elements and a Super UD-glass element.

The combination provides superb contrast and sharpness, even at the widest settings. It’s ideal for both film and digital SLRs, and features the same weatherresistant design, rear gel filter holder, and high-speed Ultrasonic Motor as the EF 16-35mm lens.

Ultra Wide Lens for Analogue EOS SLR Cameras

Ultra wide angle Canon EF zoom lens meant for professional and high amateur SLR EOS camera users.

Standard Zoom Lens for Digital EOS SLR Cameras

This can give an angle of view equivalent to that of a 28-70mm lens.

Superior Optical Performance

Super Spectra Coating on the elements ensures colour balance, minimises ghosting & flare to provide image quality.

Extensive Set of High-End Features

The AF works silently and quickly thanks to a fast central processing unit.
