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

The Sigma 85mm f/1.4 DG DN lens is a classic portrait-length prime lens designed specifically for full-frame Sony E-mount mirrorless systems. It is part of Sigma’s renowned Art line in the Global Vision series, known for its exceptional optical performance and suitability for creative and artistic applications. While primarily designed for full-frame cameras, it can also be used with APS-C models, providing a 127.5mm equivalent focal length.

With its bright f/1.4 maximum aperture, this lens excels in low-light conditions and offers extensive control over depth of field, allowing for precise subject isolation and selective focus. The optical design incorporates five Special Low Dispersion (SLD) elements, effectively minimizing chromatic aberrations and color fringing to enhance clarity and color accuracy. Additionally, one aspherical element and four high refractive index glass elements work together to control spherical aberrations and distortion, resulting in increased sharpness and accurate rendering.

A Super Multi-Layer Coating is applied to the lens elements to minimize lens flare and ghosting, ensuring contrast-rich and color-neutral imagery even in challenging backlighting situations. The integrated stepping motor delivers quick and quiet autofocus performance, further enhanced by an optimized AF algorithm for smoother focusing.

This lens offers a manual aperture ring that can be de-clicked for silent and seamless aperture adjustments, particularly beneficial for video applications. It also features a dedicated aperture ring lock switch to prevent accidental changes to the aperture setting. Additionally, it includes a built-in Autofocus-Lock (AFL) button that can be assigned additional functions, expanding the range of operations available.

The lens incorporates a rounded eleven-blade diaphragm, contributing to a smooth and appealing bokeh quality, ideal for achieving attractive background blur. Its weather-resistant construction ensures durability and reliability in various shooting conditions. The brass bayonet mount improves mounting accuracy and rigidity, ensuring a secure attachment to the camera.
