• Covering a useful wide-angle focal length range, the EF 16-35mm f/4L IS USM is a Canon L-series lens distinguished by its constant f/4 maximum aperture, sophisticated optical design, and use of image stabilization to realize sharp imagery.
• Two ultra-low dispersion elements are used to greatly reduce color fringing and chromatic aberrations throughout the zoom range for high clarity and color accuracy, and a Super Spectra coating has also been applied to suppress flare and ghosting for improved contrast.
• Three aspherical elements are also featured and help to control distortion and minimize spherical aberrations for improved sharpness. Complementing the imaging capabilities, this wide-angle zoom also features a four-stop-effective Image Stabilizer system that minimizes the appearance of camera shake for sharper handheld shooting.
• A ring-type USM and internal focusing mechanism also afford quick, quiet, and accurate autofocus performance, as well as full-time manual focus override.
