Sigma’s newest lens, designed specifically for full-frame mirrorless systems: the 85mm f/1.4 DG DN Art. Available for L-mount and Sony E-mount mirrorless cameras, this portrait-length prime lens is part of Sigma’s esteemed Art series of lenses, which prioritize optical excellence and speed. The Sigma 85mm f/1.4 DG DN lens is an all-new design specific to the mirrorless systems, and has a sleek profile that is optimized for the shorter focal flange distance of mirrorless cameras.
Compared to previous Sigma 85mm f/1.4 lenses, this new DG DN version sports a revised 15-element, 11-group optical design that incorporates a series of Special Low Dispersion (SLD), aspherical, and high refractive index elements that serve to reduce a variety of distortions and aberrations for impressive clarity and sharpness throughout the aperture range. The large-diameter design also contributes to the unique and well-corrected image quality and, of course, the bright f/1.4 maximum aperture helps to achieve the distinctive shallow depth-of-field effects to suit portraiture applications.

This 85mm f/1.4 also sports a refined exterior design, which features a physical aperture ring that can be de-clicked for smooth and silent transitions or locked to prevent accidental movements, along with a dedicated AF/MF focus mode switch and AFL button for intuitive and tactile control. In terms of autofocus, a stepping motor is used that maintains a lightweight and compact design while promoting fast and near-silent focusing performance for both stills and video applications. Additionally, the lens features an 11-blade rounded diaphragm for smooth bokeh quality, and the lens housing is weather sealed to suit working in inclement conditions.
