The Sigma 85mm EX DG HSM F1.4 is the standard for portraiture lenses. Its distinctive focal length and large aperture make it ideal for portrait and wedding photography. Designed for full frame sensors, the 85mm F1.4 is also equipped with a multitude of Sigma technology to further ensure unmatched image quality. A Hyper Sonic Motor (HSM) ensures quiet, accurate, high-speed autofocusing, Super Multi-Layer Coating to reduce flare and ghosting, and a rear focusing system to minimize fluctuation of aberration caused by focusing. Truly designed to optimize available light, it has dedicated lens hoods to block out extraneous light, glass coating for better results from backlighting scenarios, and a 9-blade diaphragm creates an attractive bokeh. - Focus on Weddings 2013
