Features:

All-in-one zoom is designed for APS-C-format Canon EF-S-mount DSLRs, and offers a 28.8-320mm equivalent focal length range.

Two ultra-low dispersion elements are used to control color fringing and chromatic aberrations in order to realize greater color accuracy and clarity.

Two aspherical elements are used to reduce distortion and spherical aberrations throughout the zoom range in order to maintain sharpness and accurate rendering.

Super Spectra coating has been applied to individual elements to minimize ghosting and flare for greater contrast and color neutrality when working in strong lighting conditions.

An Optical Image Stabilizer helps to minimize the appearance of camera shake by up to four shutter speed stops to better enable working in low-light conditions and with slower shutter speeds.

A DC Micro Motor autofocus system provides quick focusing performance and a dedicated AF/MF switch allows for quick switching between auto and manual focusing methods.

Rounded six-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
