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.
Designed to deliver ultra-high quality images along with lightning fast operation, the new Canon EF 70-300 f/4-5.6L IS USM telephoto zoom lens brings a favorite zoom range to the celebrated Canon L-series of lenses. It features two Ultra Low Dispersion (UD) elements for improved image quality and reduced chromatic aberration, incorporates a floating focusing mechanism for sharpness from close up to infinity, plus an IS system that increases usability by approximately four stops.
The EF 70-300 f/4-5.6L IS USM features a function that prevents erroneous operation when the lens is mounted on a tripod or monopod. Gleaming white, with a removable tripod collar, dust and water resistant construction, and a newly developed Fluorine coating that keeps soiling, smears and fingerprints to a minimum, its phenomenal performance and flexibility is assured. For portraiture or to bring what's far away up close, this addition to the L-series is guaranteed to perform.
