EF 28mm f/1.8 USM

This Canon EF 28mm f/1.8 USM is a wide-angle prime lens designed for full-frame Canon EF-mount DSLRs, though it can also be used on APS-C bodies where it provides a 44.8mm equivalent focal length. The bright f/1.8 maximum aperture enables effective low-light performance and precise control over depth of field for selective focus techniques. The optical construction includes one aspherical element that minimizes distortion and spherical aberration to deliver sharp, accurate image rendering.

The lens incorporates a Super Spectra coating on its elements to reduce flare and ghosting while maintaining contrast and color neutrality in strong lighting conditions. A ring-type Ultrasonic Motor provides fast and quiet autofocus performance alongside full-time manual focus override capability. The rounded seven-blade diaphragm produces pleasing bokeh quality that complements shallow depth of field applications.
