The EF 16-35mm f2.8L II USM is a high performance, water-resistant,
and ultra wide-angle Canon L-series lens. It has been specifically
designed for improved edge-to-edge image quality that will meet
the strict requirements of professional and high-end amateur
photographers. It features 3 high-precision aspherical lens elements,
each of a different type: ground, replica and GMo for even better
image quality than the original EF 16-35mm f2.8L USM. The circular
aperture produces a beautiful and natural background blur when
shooting at wider apertures. Other features include internal
focusing, a ring type USM (Ultra Sonic Monitor), and new AF algorithms
for fast and quiet autofocusing.
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.
A fast f2.8 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.
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.
A circular barrel aperture helps to create attractive, even
background bokeh when isolating subjects at wide apertures.
The EF 16-35mm f2.8L 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 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.
The lens passes distance information back to the camera's E-TTL
II flash system for consistently accurate flash metering.
