The Canon EF 16-35mm f/2.8L II USM Autofocus
Lens is a high performance, water-resistant, and ultra wide-angle L-series
lens. The optical design has been improved to offer better edge-to-edge
image quality. In addition, it features 3 high-precision aspherical lens
elements, each of a different type: ground, replica and GMo. Improved AF
algorithms will help the lens to focus faster and quieter.
All of the "L" lenses deliver
optical performance equal to similar fixed focal lengths lenses, and the
USM lenses do this with silent, high-speed focusing. Distortions and
aberrations are remarkably small for a lens of such amazing capabilities.
Key Features
• Entirely internal focusing and zooming
movement
• Ring-type USM provides ultra-quite,
super-fast, precision auto focusing and predictive tracking
• Fulltime manual focus override (even in
AF mode)
• Circular aperture diaphragm produces
brilliant out-of-focus characteristics
