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. At a featherweight 4.6 oz, this is one of the lightest lenses in the EF family. It is less than one inch long, so it will never draw unwelcome attention to you when you are shooting in public. A bright f/2.8 maximum aperture allows you to shoot under pretty much any lighting conditions, and the sophisticated lens configuration, including one aspherical element, guarantees high image quality from the center to the edge of the frame.
