Canon EF 16-35mm f/4L IS USM Lens

Introducing a wide-angle focal length range, the Canon EF 16-35mm f/4L IS USM L-series lens well known for its constant f/4 maximum aperture, urbane optical design, and use of image stabilization to obtain sharp imagery. Two ultra-low dispersion elements are used to greatly minimize color fringing and chromatic aberrations all over the zoom range for high clarity and color accuracy, and a Super Spectra coating has also been applied to decrease flare and ghosting for upgraded contrast. Three aspherical elements are also featured and help to reduce distortion and minimize spherical aberrations for improved sharpness in the image.

Applauding the imaging capabilities, this wide-angle zoom also features a four-stop-effective Image Stabilizer system that reduces the camera shake for sharper handheld shooting. A ring-type USM and internal focusing mechanism also get quick, quiet, and accurate autofocus performance, as well as full-time manual focus override. The lens is weather-sealed and has a protective fluorine coating on the exposed elements used for working in different environmental conditions.

• Wide-angle zoom is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 25.6-56mm equivalent focal length range.

• Constant f/4 maximum aperture maintains consistent illumination throughout the zoom range.

• Two ultra-low dispersion glass elements noticeably reduce color fringing and chromatic aberrations for high clarity and color fidelity.

• Three aspherical elements minimize spherical aberrations and distortions for improved sharpness and accurate rendering.

• Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.

• An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds.

• A ring-type Ultrasonic Motor (USM), along with an internal focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.

• The rounded nine-blade diaphragm helps to get a better focus quality that eases the use of shallow depth of field and selective focus techniques.

• A protective fluorine coating has been applied to the front and rear elements of the lens to resist fingerprints and smudges on the glass.

• This lens is dust and moisture-protected which made it perfect for working in difficult environmental conditions.
