CANON Camera Lens EF 17-40mm F/4 L USM

This super wide-angle zoom lens allows you to take wide photographs even with digital SLR cameras which have a screen size smaller than 35mm, covering the range from a super wide-angle 17mm to a standard 40mm. Three aspherical lens elements which come in two types deliver both a wide zoom range and high image quality, while the super UD lens elements provide excellent correction of the magnification-type chromatic aberration. Innovations such as a lens coating optimized for digital photography help minimize flare and ghosts, which often occur with digital cameras.
