This lens structure consists of one fluorite and 5 ultra-low spreading optical elements that help deliver the sharpness and minimize aberrations. The IS II Optical Image Stabilizer gives up to four stops of modification at all focal lengths and has two modes for stabilization of unmoving objects and while panning to follow moving subjects. An ultrasonic focusing motor offers rapid, smooth and quiet autofocus action.

Like every Canon L-series lenses, this telephoto zoom is dirt and wetness resistant and built to keep on going even in the most demanding environments. Fluorite and ultra-low scattering lens elements decrease aberrations and contribute to high value of resolution, high-contrast imaging. Dual mode Image Stabilization is accurate for all kinds of camera shake. Mode 1 corrects for stationary images and Mode 2 for the inappropriate up and down movement formed when panning with moving subjects. An ultrasonic autofocus motor gives quick, smooth and almost quiet autofocus. Manual focus override allows exact manual focus in autofocus mode as well. A focus range limiter enables you set the range of focus distance that lets shorter focusing times. The two ranges are 8.2′ to infinity and 3.9′ to infinity. A truly circular aperture hole results in more pleasant out-of-focus regions. Firm seal structure makes sure excellent dirt-proof and moisture-proof performance. Detachable, rotatable tripod collar is incorporated.
