A practical and versatile prime, the EF 28mm f/2.8 IS USM Lens from Canon pairs the wide-angle focal length with sophisticated autofocus capabilities as well as image stabilization. The optical design utilizes one aspherical element to reduce spherical aberrations and distortion for high sharpness, and a Super Spectra coating has also been applied to suppress flare and ghosting for increased contrast and color accuracy. Benefitting the optics is a four-stop-effective Image Stabilizer, which minimizes the appearance of camera shake for sharper handheld images. Also, a ring-type USM realizes quick, quiet, and smooth autofocus performance along with full-time manual focus override.

Wide-angle 28mm f/2.8 lens is designed for full-frame Canon EF-mount DSLRs, however can also be used with APS-C models where it provides a 44.8mm equivalent focal length.
Bright f/2.8 maximum aperture benefits working in low-light conditions and also permits working with shallow depth of field techniques.
One aspherical element helps to suppress spherical aberrations and distortion for a high degree of 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 ring-type Ultrasonic Motor (USM) is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
Rounded seven-blade diaphragm contributes to a pleasing out of focus quality that benefits the use of shallow depth of field and selective focus techniques.
