Sigma 85mm f/1.4 DG HSM Art Lens for Sony E

The Sigma 85mm f/1.4 DG HSM Art Lens for Sony E is a portrait-length prime lens designed for full-frame Sony E-mount mirrorless cameras, developed as a native Sony E-mount version of Sigma’s acclaimed Art-series 85mm f/1.4, built with a control algorithm specifically optimized for mirrorless autofocus drive and data transmission speed rather than simply adapting the DSLR version via a mount converter. It’s aimed at portrait, wedding, and fine art photographers who want exceptional sharpness, background rendering, and build quality from a classic portrait focal length.

Optically, the lens is built from 14 elements in 12 groups, including two SLD (Special Low Dispersion) elements and one element with a high rate of anomalous partial dispersion and high refractive index, working together to thoroughly correct aberrations for high resolution and accurate color rendering. The fast f/1.4 maximum aperture enables strong low-light performance and pronounced control over depth of field for isolating subjects using selective focus, while a rounded 9-blade diaphragm contributes to smooth, pleasing bokeh.

Autofocus is handled by Sigma’s Hyper Sonic Motor (HSM), delivering fast, quiet focusing performance, along with full-time manual focus override available simply by rotating the focus ring at any time. Build quality uses a combination of aluminum and Sigma’s Thermally Stable Composite (TSC) material, along with a brass bayonet mount for improved accuracy and durability. The lens has a minimum focusing distance of 2.79 ft. (85cm), yielding a maximum magnification ratio of approximately 1:8.5, and accepts a 77mm filter thread. It measures approximately 94.7mm in diameter by 152.2mm in length and weighs approximately 1,210g, notably larger and heavier than most other 85mm lenses available for Sony’s mirrorless system.

As a full-frame E-mount lens, the Sigma 85mm f/1.4 DG HSM Art delivers its full angle of view (28.6°) on Sony full-frame bodies while remaining compatible with Sony APS-C E-mount cameras at a narrower, 127.5mm-equivalent effective field of view.
