SPECIFICATIONS:

• 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.
