Expanded Sigma 85mm f1.4 Art DG HSM Lens - Sigma Fit Key Features:

Exclusive Low-Dispersion Glass

This lens eliminates chromatic aberration as well as residual chromatic aberration also knows as "secondary spectrum". The lens includes up to three types of exclusive low-dispersion glass: Extraordinary Low Dispersion (ELD), Special Low Dispersion (SLD), and "F" Low Dispersion (FLD). Thanks to these as well as the optimised power distribution this lens provides the user with excellent image rendition which remains unaffected by residual chromatic aberration.

HSM for Nimble AF Control

This lens offers terrific speed and exceptionally stable performance even at lower speeds thanks to the large hypersonic motor (HSM) that is 1.3 times the torque of its predecessor. Working in combination with the optimised AF algorithm, this characteristic equips the user with the perfect tool for fast autofocus photography. The user can switch to manual focus by simply rotating the focus ring thanks to the full-time manual focus function even during continuous AF.

Compatibility:

• Compatible with SIGMA USB DOCK for customisation and flexible adjustment
• Works with MC-11 Mount Converter which allows for the use of SIGMA SA mount and SIGMA EOS mount (Canon compatible) interchangeable lenses with the Sony E-mount camera body
