Sigma Ships 85mm f/1.2 DG Art at $1,599 for Sony E and L-Mount

Sigma has launched the 85mm f/1.2 DG DN Art for Sony E and L-mount at $1,599, shipping now and claiming the smallest, lightest build in the 85mm f/1.2 class. The price positions the lens well below most first-party f/1.2 fast-portrait options, and Sigma says the 905 g (2 lb) weight undercuts every direct competitor except one near-tie from Mitakon.

The target buyer is explicit: portrait and event photographers who want Art-series optical performance in a full-frame f/1.2 prime without a tank-sized body. Sigma announced the launch on October 28, 2026.

What are the hard specifications?

The optical formula runs 17 elements in 12 groups, with two SLD (special low dispersion) elements and three aspherical elements controlling chromatic and spherical aberration. Sigma engineered the design to suppress focus breathing, a decision aimed squarely at video shooters working events and staged portraits.

The 13-blade rounded diaphragm keeps bokeh smooth and circular even after stopping down, rather than producing polygonal highlight shapes. The lens covers full frame, offers a 28.6° angle of view, focuses to 2.8 ft / 84 cm, and delivers 0.11x magnification (1:8.9 reproduction). Filter threads are 82 mm front, minimum aperture is f/16, and dimensions come in at 87.2 x 121.7 mm. There is no image stabilization — bodies carry that burden.

Autofocus runs on dual HLA (High-response Linear Actuator) motors, with Sigma promising fast, quiet and precise focus. The reviewer notes that Sigma Art lenses, including older generations, have a strong autofocus track record. Physical controls include an AF/MF switch, an aperture click/de-click switch, and a ring-lock button — the de-click option matters for anyone recording video with in-lens aperture pulls.

How does the weight claim hold up?

The 905 g figure needs context. Sigma's own 18-35mm f/1.8 Art weighs 810 g, so the new 85mm is no featherweight in absolute terms. But among 85mm f/1.2 lenses, the claim checks out against the named competition: Nikon, Canon and Sony 85mm f/1.2 options all weigh over 1,100 g. The Mitakon Zhongyi Speedmaster 85mm f/1.2 lands at 921 g — nearly identical to Sigma's number — but Sigma holds the edge at 16 g lighter, along with full autofocus and a full manufacturer's feature set.

What does this change for working photographers? For Sony E shooters, it adds one of very few autofocus 85mm f/1.2 options on the market, and one of the cheapest lenses this fast in the focal length. For L-mount shooters, it expands fast-portrait selection at a price point below the first-party alternatives.

Pricing and availability

The Sigma 85mm f/1.2 DG DN Art is available now for Sony E and L-mount at $1,599. Independent tests of the claimed aberration control and bokeh rendering will determine whether the Art badge holds up in deliverables, but on paper the price-to-weight ratio sets a new reference point for the class.
