EF 70-300mm f/4-5.6 L IS USM

The Canon EF 70-300mm f/4-5.6L IS USM is a telephoto zoom lens designed for Canon EF-mount DSLRs that delivers versatile focal length coverage in a relatively compact and lightweight design. The lens incorporates two ultra-low dispersion elements and Super Spectra coating to minimize color fringing and flare while maintaining high clarity and contrast across the zoom range. An internal floating focus mechanism ensures consistent optical performance from the 3.94-foot minimum focus distance to infinity, while a four-stop-effective optical image stabilizer enables sharper handheld shooting in various lighting conditions.

Autofocus performance is delivered through a ring-type ultrasonic motor that provides fast and quiet focusing with full-time manual focus override, and the lens benefits from a rounded eight-blade diaphragm for pleasing out-of-focus rendition. As part of Canon's L-series, the lens features weather-sealed construction with a protective fluorine coating on the front and rear elements to resist dust, moisture, fingerprints, and smudges. An optional rotating tripod collar is available to facilitate use on tripods or monopods.
