Canon’s engineers have completely redesigned the optics on the EF 16 35mm f/2.8L II USM to deliver higher contrast levels and improved resolving power. To ensure corner-to-corner sharpness and contrast throughout the focal range, the lens includes three types of aspherical lens elements (ground, replicated and glass moulded). Two UD lens elements virtually eliminate chromatic aberration, while Super Spectra lens coatings suppress flare and ghosting.

Rapid auto focus is driven by a virtually silent Ring-type Ultrasonic Motor (USM) incorporating Canon’s latest auto focus algorithms. Full-time mechanical manual focus override is also provided. As with all L-series lenses, the EF 16 35mm f/2.8L II USM is weather sealed to protect against dust and moisture.

A new 82mm Protect filter for the EF 16 35mm f/2.8L II USM has been released to coincide with the launch.
