SIGMA 85mm F1.4 DG HSM Art

Aimed at portrait photographers and those who want to create dramatic shallow depth of field effects, this full-frame 85mm lens in Sigma�s Art series employs two FLD (fluorite equivalent) elements and one anomalous-dispersion (AD) high-refractive index element to achieve extremely low levels of chromatic aberration. The lens contains a 9-bladed electronically controlled diaphragm, a hypersonic (HSM) motor for rapid and silent AF, and an AF system with 1.3X torque boost. Quality build features include a durable brass mount and a composite TSC barrel, a material known to provide consistent performance at extreme temperatures and is considerable lighter than other materials that would yield similar benefits.
