The Sigma 8-16mm f/4.5-5.6 DC HSM Ultra-Wide Zoom Lens for Sigma Cameras is an ultra-wide zoom that has a 35mm equivalent angle of view of a 12-24mm lens when used on DSLRs with APS-C size image sensors. Sigma's FLD glass elements, equal to fluorite glass, correct for distortions and color aberrations to deliver beautiful high contrast images.
The lens has a minimum focusing distance of 9.4" (24cm) allowing you to get in close to a subject to create exaggerated perspectives. This super wide angle zoom is perfect for shooting landscape photography, architecture, building interiors, photojournalism, wedding photography, group pictures and a wide variety of other shooting opportunities you may encounter. A lens hood is permanently attached to the lens.
