Compact and lightweight, yet durable and professionally sharp, the EF 70-300mm f/4-5.6L IS USM lens is the ideal telephoto zoom lens for advanced amateurs looking for that extra reach to bring a subject in tight and close. Providing the power and durability to maximize every shooting opportunity, the Canon EF 70-300mm f/4-5.6L IS USM lens features two UD ultra-low dispersion glass elements for enhanced sharpness, L-series weather and dust sealing for shooting in harsh conditions, improved mechanical design, and streamlined ergonomics to help avoid inadvertent mode switch operation. The shapes of the lens elements and their coatings have been optimized to minimize ghosting and flare to produce high-contrast and high-resolution throughout the zoom range. A sophisticated floating system optical formula optimizes image quality at all distance settings and reduces minimum focusing distance by more than a foot. An updated optical image stabilization system compensates for camera shake up to an equivalent of four full shutter-speed steps, a full step improvement compared to earlier EF 70-300mm lenses. A new fluorine anti-smear coating is applied to the front and rear elements.
The Canon EF 70-300mm f/4-5.6L IS USM lens is expected to be available toward the end of October for an approximate retail price of $1,500.
