The Canon EF 16-35mm f/4L IS USM Lens is a wide-angle zoom lens that delivers the ultimate combination of wide-angle, low-light performance, L-series optics, and compact construction. The new Canon EF 16-35mm f/4L IS USM lens is a phenomenal complement to any EOS SLR camera. This L-series ultra wide-angle zoom incorporates an Optical Image Stabilizer, and offers up to four stops of correction for admirable performance even in dim light. It features three aspheric lens elements and two UD lens elements to minimize aberrations throughout the zoom range, plus a fluorine coating that helps to minimize ghosting. A circular 9-blade aperture delivers gorgeous background blur. The EF 16-35mm f/4L IS USM features inner focusing and ring USM for accurate, discreet and speedy AF. It also offers full-time manual focus and has a minimum focusing distance of 0.92 ft./0.28m across the entire zoom range.

Wide Angle Zoom
This Canon L-Series lens can be used on both full-frame and APS-C sensors and features a constant f/4 maximum aperture for consistent performance throughout the zoom range.
USM AF Motor
For fast, smooth, and near-silent autofocus performance, a ring-type USM (Ultrasonic Motor) AF motor is used. An internal focusing design maintains the overall length of the lens during use. Full-time manual focus override can also be utilized for fine-tuned focusing precision as closely as 11" throughout the zoom range.
Optical Image Stabilizer
Minimizes the appearance of camera shake by up to four stops for improved usability in difficult lighting conditions.
Nine-Blade Circular Diaphragm
Helps create an aesthetic out-of-focus or bokeh effect.
Manual Focus
Full-time manual focus provides crucial focusing precision, even in AF mode.
Aspherical Elements
The optical design incorporates three aspherical elements, including one large-diameter aspherical element, as well as two UD (Ultra-low Dispersion) elements to minimize chromatic aberrations and contribute to high edge-to-edge sharpness and resolution.
Dust and Water Resistant
Apply an optional 77mm Protect filter to make the lens dust and water resistant to gel protect the lens from environmental elements.
Fluorine Coating
The fluorine coating on the front and rear lens surfaces reduces flare and ghosting for maintained color neutrality and image contrast.
