L-series quality
The lens embodies Canon's highest standards of L-series optics, build quality, reliability and operability. A robust construction includes dust and moisture resistant seals to protect against harsh weather conditions.

Constant f/2.8 aperture
A fast f/2.8 aperture delivers impressive low light performance and depth-of-field control. The aperture is fixed over the full focal range, allowing photographers to maintain a constant fast shutter speed when zooming.

Fast, quiet auto focus
A ring USM (Ultrasonic Motor) drives extremely rapid auto focus with near-silent operation. Full time mechanical manual focus override is available without having to switch out of AF. The lens offers a minimum focusing distance of 0.28m throughout the zoom range.

Good background bokeh
A circular barrel aperture helps to create attractive, even background bokeh when isolating subjects at wide apertures.

UD and aspherical elements
The EF 16-35mm f/2.8L II USM incorporates three aspherical elements to ensure corner-to-corner sharpness and clarity throughout the focal range. Two UD (Ultra Low Dispersion) elements virtually eliminate chromatic aberrations.

Super Spectra coatings
Super Spectra lens coatings suppress flare and ghosting - more prone to occur with digital cameras due to reflection off the image sensor. Coatings also help maintain accurate colour balance and high contrast.

Passes distance information to E-TTL II
The lens passes distance information back to the camera's E-TTL II flash system for consistently accurate flash metering.

Accessories
The EF 16-35mm f/2.8L II USM lens comes supplied with a lens hood and soft case.

Light and fast
The small size and low weight of the EF-S 17-85mm f/4-5.6 IS USM make it ideal for fast moving photography and travel, where it is not practical to carry around a heavy bag of kit. Its ring-type USM works in concert with EF-S mount EOS cameras to provide super-fast, precision auto focusing and predictive tracking - with full manual override available at any time.

Go steady
Image Stabilizer technology compensates for a full three stops, giving the lens an effective maximum aperture of f1.4-2.0; excellent for hand-held and low light photography.

Designed for digital
Designed specifically for digital photography, the lens has specially shaped lens elements and Super Spectra coatings to suppress ghosting and flare, which can be caused by reflections off digital camera sensors. An exclusive optional lens hood can further reduce the incidence of flare.

Background blur
A circular aperture provides a pleasing background blur when shooting with a wide aperture; ideal for creating a sense of depth and getting your subject or model to stand out from the background.
