Capture high-quality pictures with your Canon EF series cameras by using the Sigma DG HSM Art Lens. It features a focal length of 20 mm and a maximum aperture f/1.4 that delivers a better bokeh effect and outstanding visual clarity. The advanced Hyper Sonic Motor enables the lens to provide a high-speed autofocus for focusing better on the subject to be captured. The lens’ Super Multi-Layer coating helps in reducing unwanted ghosting and flare for those sharp, high contrast images even in backlit conditions. Since it is made from high-quality materials, this lens is extremely durable.
