Standard zoom is designed for APS-C-format Canon EF-S-mount DSLRs, and offers a 27.2-136mm equivalent focal length range.
One dual-sided aspherical element minimizes spherical aberrations and distortions for improved 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 three stops to better enable working in low-light conditions and with slower shutter speeds.
A ring-type Ultrasonic Motor (USM), along with an internal focusing system, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
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.
