Fast Normal-Range Zoom. The 24-70mm focal length is the bread and butter for many types of photography due to the wide to portrait-length range it covers. The fast f/2.8 aperture offers both depth-of-field control and flexibility for shooting in low light.

Silent Wave Autofocus Motor. The Silent Wave Motor provides quick, quiet, and precise autofocus performance for both still and video shooting. The internal focusing design retains the overall lens length during operation while contributing to a lighter overall weight. Full-time manual focus override is as simple as rotating the focus ring at any time.

Vibration Reduction. By far the biggest addition, this in-lens stabilization system offers up to 4 stops of correction to help combat camera shake.

Electromagnetic Aperture. Provides greater exposure control stability, which is especially beneficial when working with fast continuous shooting rates.

Updated Optics. The optical formula has been revised from its predecessor’s design. This includes a single unique aspherical extra-low dispersion element, three aspherical elements, one high refractive index element, and two extra-low dispersion glass elements that combine to minimize aberrations, distortion, coma, and flare.
