SIGMA'S WIDEST ULTRA-WIDE-ANGLE ZOOM 
 
Designed for use with full-frame DSLRs, the 12-24mm is a wide-angle zoom that offers an exceptionally wide focal length for anyone needing a very wide angle-of-view. The lens is perfect for landscape photography, interiors, events and architecture, and the constant F4 aperture provides fast shutter speeds in low light.
 
Optically the lens is extremely impressive, delivering edge-to-edge sharpness even at 12mm, allowing photographers to capture scenes in remarkable detail, even on the highest resolution DSLR cameras. This is thanks to its advanced optical design that includes 5 FLD elements, 1 SLD element and 2 aspherical elements.
 
The SIGMA 12-24mm F4 lens also features a durable and weather-resistant design, making it suitable for use in a variety of shooting conditions.
