Sigma 85mm f/1.2 DG Art Review: A New Benchmark for Portrait Lenses

Sigma has introduced its first-ever 85mm f/1.2 lens, the DG Art, available in Sony E-mount and Leica L-mount, marking a significant entry into a market previously dominated by manual-focus options. The lens, priced at $1,699, is lighter than comparable Canon and Nikon versions, weighing only 905 grams (32 ounces) compared to their 1,200 grams (42 ounces), and is claimed by Sigma to be the world's lightest and smallest full-frame 85mm f/1.2 lens. The review highlights its exceptional optical performance, including minimal longitudinal chromatic aberration (LoCA), beautiful bokeh with no onion rings, and a slight veiled flare that is desirable for backlit portraits. The lens features a fast HLA (high-speed linear actuator) motor, a customizable button, and a full aperture ring that can be de-clicked. It is weather-sealed and robust, with an 82mm filter diameter. The focusing speed is quick, and a floating element reduces lens breathing, making it suitable for video work. The review notes that while the lens is a specialty item, it excels at f/1.2, delivering dreamy contrast and sharpness when stopped down slightly. The author concludes that it is the only autofocus 85mm f/1.2 lens available for E-mount and L-mount, making it a nearly perfect choice for those who regularly shoot at that aperture.
