The EF 35mm f/2 IS USM Lens from Canon is a wide-angle prime lens with a fast maximum aperture. It is ideal as an everyday lens and is very effective in low light conditions
The lens′ ring-type ultrasonic motor (USM), rear focusing system, and high-speed CPU--with optimized AF algorithms--ensure that you experience quick, quiet and precise autofocus action. Its circular eight-bladed diaphragm gives pleasing, soft background effects, and a Glass Molded (GMo) aspherical lens element minimizes aberrations and contributes to higher image quality out to the edges of the frame.
Adjust focus using either autofocus (AF), or full-time manual focus, without having to switch modes or change camera settings. Optical Image Stabilization (IS) gives up to 4 shutter speed stops of compensation against the blur caused by camera shake, providing clearer images when shooting in low light. A micro-stepping drive provides quieter operation and a low speed focus drive delivers optimal results when shooting video.
