One Super ED element and two extra-low dispersion elements are featured in the lens design and help to reduce chromatic aberrations and color fringing for improved clarity and color neutrality.

Nano AR Coating II has been applied to reduce surface reflections, flare, and ghosting for increased contrast and color rendering in strong lighting conditions. This updated coating is better suited for larger, curved elements and is especially adept at minimizing internal reflections.

An XD Linear Motor system uses two separate motors, along with an internal focusing design, to provide quick, quiet, and precise autofocus and tracking performance. This design also contributes to more natural, intuitive Linear Response manual focus control and an AF/MF switch is located on the lens barrel for quick focus mode switching.

Minimum focusing distance of 9.8" suits making dynamic close-up images.

A focus hold button is present on the lens barrel for intuitive tactile control and rapid access to select programmable settings.

Physical aperture ring can be de-clicked for smooth, silent aperture switching to benefit video applications. The ring also incorporates a locking "A" position for use in automated exposure modes.

Dust- and moisture-sealed design better permits working in inclement conditions and rubberized control rings benefit handling in colder temperatures.

Fluorine-coated front and rear elements resist dust, moisture, and fingerprints and are easy to clean.

Filter holder is incorporated at the rear of the lens, within the lens mount, and accepts cut gel filters and a filter cutting template is included.

Integrated petal-shaped lens hood helps to block stray light from causing lens flare and also affords some physical protection to the front element.

Vibration Reduction image stabilization helps to reduce the appearance of camera shake to better enable handheld shooting in low-light situations.

Multi-focus system incorporates two separate AF drive units, which are synchronized, to deliver especially fast and accurate focusing throughout the zoom range. This system uses stepping motors, which offer impressively smooth and quiet autofocus performance that is well-suited to both stills and video applications. Full-time manual focus override is also possible and an internal focusing design is used, where only the internal lens groups are moved during focusing, to maintain the overall length of the lens during use and to promote faster focusing speeds.

Programmable Control Ring is, by default, set to adjust manual focus, but can also be used to control aperture or exposure compensation.

Integrated OLED lens information panel allows you to quickly confirm aperture setting, focus distance, and depth of field figures right on the lens in both bright and dark situations.

Two assignable L.Fn buttons work in conjunction with camera-based Fn buttons to provide seamless points for quickly changing exposure settings and other functions.

Specialized electromagnetic aperture mechanism provides greater exposure control stability that is especially beneficial when working with fast continuous shooting rates.

Dust- and moisture-resistant lens barrel, along with a front fluorine coating, benefits the lens' use in inclement conditions.

Removable, rotating tripod collar spins on ball bearings to permit quick and smooth switching from vertical to horizontal shooting orientations.
