The EF70-200mm f/4L IS USM Lens - Versatile and Compact EF Lens

The EF70-200mm f/4L IS USM lens delivers the legendary sharpness and clarity of the Canon 'L' series lenses in a compact and lightweight design that is easy to use for hand held photography, making it a versatile lens for any photographer

Canon is the only manufacturer to provide a full range of professional zoom lenses in both the high-speed f/2.8 category as well as the compact and lightweight f/4 category. Rounding out Canon's f/4L lens lineup is the EF70-200mm f/4L IS USM lens.

This "L" series lens is designed for professional or advanced amateur photographers seeking maximum performance and versatility. This is a lens that can handle almost any assignment, ranging from distant subjects to the demanding requirements of up-close and personal portraits as well as nature photography.

The EF70-200mm f/4L IS USM lens stands up to the rigors of professional use. The lens is sealed from dust and moisture, and is equipped with the latest generation of Canon's Image Stabilizer (IS) technology, making it an optimal everyday shooter.

The image stabilization achieves three shutter speed steps of camera shake correction within 0.5 seconds after the shutter button is depressed halfway and yields correction for up to four full shutter speeds while handheld, providing a new level of performance. Users can also select two IS modes, one for stationary subjects and another for intentional panning.

The EF70-200mm f/4L IS USM lens is the same size as the EF70-200mm f/4L USM lens that remains in the EF lens line, but the new lens adds several valuable features. In addition to enhanced weather sealing and image stabilization, the EF70-200mm f/4L IS USM lens incorporates a circular diaphragm to create more natural looking background blur, and distance information to aid autofocusing and automatic flash exposure.

The lens also suppresses flare and ghosting with advanced coatings and optimal placement of its 20 lens elements in 15 groups. One Fluorite element and two UD (ultra low dispersion) elements thoroughly suppress chromatic aberrations for crisp photos throughout the entire focal range.

A ring-type Ultrasonic Motor (USM) provides fast and silent autofocusing, while the full-time manual focus function provides maximum control even when the lens is set for AF.
