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.
