Sigma Previews 85mm F1.2 DG Art Development, Completing Mirrorless F1.2 Prime Trio

Is there such a thing as too much speed? For an 85mm lens, maybe, but you'll rarely catch a working DP or AC complaining about having an f/1.2 option in their kit. Sigma has just announced the development of its 85mm F1.2 DG Art lens, a medium-telephoto prime for full-frame mirrorless cameras (L-Mount and Sony E-mount). This marks the completion of their f/1.2 Art prime lineup, joining the 35mm F1.2 DG II Art and the 50mm F1.2 DG DN Art. The lens is being shown as a development prototype at CP+ 2026 in Yokohama, Japan, with a planned launch in September 2026.

This announcement isn't just about a single lens; it's about Sigma solidifying its offering for cinematographers and filmmakers who demand extreme light gathering and shallow depth of field from their primes. For years, the 85mm focal length has been a staple in portraiture and narrative filmmaking, revered for its flattering perspective and ability to separate subjects from complex backgrounds. Now, with an f/1.2 option from Sigma, along with existing offerings from Canon and Nikon, the options for achieving that ultra-creamy bokeh are broadening across mirrorless platforms.

What's Known About the 85mm F1.2 DG Art So Far

As this is a development announcement, concrete specifications are still sparse. Sigma has stated that the 85mm F1.2 DG Art will feature a new optical design engineered for exceptional resolution, even when shooting wide open at f/1.2. This is a critical point for professionals. While a fast aperture is appealing, if the lens can't maintain sharpness and contrast at its widest settings, its practical utility diminishes rapidly for narrative work. We've all seen beautiful images shot wide open, but we've also dealt with lenses that introduce spherical aberration and chromatic distortion until you stop them down a full two stops. Sigma's "Art" designation generally implies a high standard in optical performance, so the expectation for sharp, clean images at f/1.2 is significant.

One of the more practical details released is the inclusion of a dual HLA (High-response Linear Actuator) autofocus system. This motor technology is already present in Sigma's most recent Art lenses, including the Sigma 35mm F1.4 DG II Art, which was also recently revealed ahead of CP+ 2026. This is good news for video shooters because the dual HLA system has a track record of delivering fast and quiet focusing. In a world where even high-end productions are increasingly relying on sophisticated autofocus tracking for certain shots (think Steadicam or gimbal work where a focus puller's reaction time might be stretched), responsive and silent AF is no longer a luxury, but a necessity. The last thing you want is focus motor noise bleeding into your dialogue tracks, or a slow autofocus system hunting during a critical take.

The lens will utilize an 82mm front filter thread. This commonality across several other Sigma Art lenses (like the 28-45mm f/1.8 DG DN Art and the 28-105mm f/2.8 DG DN Art) is a pragmatic consideration. For DPs and camera assistants, standardizing filter sizes leads to less gear to carry and fewer expensive filters to purchase. You can invest in a high-quality 82mm ND or polarizer and then use step-down rings to adapt it to lenses with smaller diameters. It's a small detail, but these workflow efficiencies add up on set.

Sigma also emphasizes a "compact and lightweight body" for the new 85mm f/1.2. This will be interesting to see in practice. Pushing from f/1.4 to f/1.2 typically requires significantly larger and heavier glass elements to maintain optical quality and gather that extra third of a stop of light. The existing Sigma 85mm F1.4 DG DN Art, for instance, weighs a mere 630g, making it one of the most svelte 85mm lenses on the market. How Sigma manages to achieve an f/1.2 aperture while maintaining a "compact and lightweight" form factor will be a key factor for many cinematographers and gimbal operators, who often prioritize size and weight alongside optical performance.

The Competitive Field & What F1.2 Means for Filmmakers

The 85mm F1.2 focal length isn't uncharted territory. Canon has long offered their RF 85mm F1.2 L USM (and a Defocus Smoothing variant) for their RF mount system, which has been a go-to for many portrait and narrative shooters. Nikon also competes in this space with their Nikkor Z 85mm f/1.2 S. With Sigma's entry, all four major full-frame mirrorless mounts (Canon RF, Nikon Z, L-Mount, and Sony E-mount) will have a native 85mm F1.2 option. This growing competition is generally beneficial for filmmakers, as it often drives innovation and competitive pricing.

For video shooters, a fast 85mm prime lens is an indispensable tool. It excels in situations requiring strong subject isolation, such as:

- Interviews: The shallow depth of field at f/1.2 can create incredibly cinematic backgrounds, making the subject pop with a dreamlike quality.
