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.
