A classic portrait-length lens updated for full-frame Sony E-mount mirrorless systems, the Sigma 85mm f/1.4 DG DN is an Art-series prime characterized by its advanced and updated optical design, sleek profile, and bright design. The f/1.4 maximum aperture enables working in low-light conditions and also provides increased control over depth of field for achieving shallow depth of field effects. The optical layout incorporates a series of low dispersion, aspherical, and high refractive index elements and its large diameter design achieves a notable degree of clarity and sharpness with well-controlled distortion and aberrations. Also, a Super Multi-Layer Coating enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions.
Balancing the optics is a refined exterior design, which features a physical aperture ring, which can be de-clicked or locked, along with a dedicated focus mode switch and AFL button for intuitive and tactile control. For 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 also weather-sealed to suit working in inclement conditions.
