The used Canon 28mm f/2.8 IS USM is a small, lightweight wide-angle lens for Canon DSLRs. It’s a wonderful low-cost lens for still and video shooters. Key features include:

Lightweight, Stabilized Wide-Angle Lens. The Canon 28mm f/2.8 IS USM is a small, lightweight wide-angle option for Canon DSLRs that features a built-in image stabilizer offering up to 4 stops of correction. With this stabilization, its f/2.8 aperture is plenty fast for many shooting situations, and the ring-type USM focusing motor allows for fast, near-silent autofocus performance.

Superb Image Quality. This rear-focusing lens remains a mere 2.02" in length throughout use. The image quality produced is quite high, with an aspherical element used to provide high levels of corner sharpness and coated optics to minimize ghosting and flare. This is a wonderful low-cost lens option for both still and video shooters.
