This EF 40mm f/2.8 STM Lens from Canon is a welcome addition to Canon's line-up of EF lenses--a light, inconspicuous "normal" lens.
STM functionality provides quiet, smooth and continuous autofocus during video operation (continuous video autofocus only when used with the Canon EOS 70D, Rebel T4i and T5i). The circular aperture formed by 7 diaphragm blades combined with the wide aperture can give you beautiful bokeh--the out-of-focus background areas of your images. This 40mm lens will give you a view equivalent to 64mm when used on a camera with an APS-C sensor, and is able to focus as close as 11.81".
