Overshadowed slightly by the release of the pocket-sized Sigma fp full-frame mirrorless camera, last night, Sigma also announced three lenses we knew were coming. The full-frame Sigma 14-24mm f/2.8, 35mm f/1.2, and 45mm f/2.8 DG DN lenses designed for the L-mount and Sony E-mount.
Part of a “newly developed” selection of Art, Contemporary and Sport lenses for full-frame mirrorless cameras, the first three lenses add some compelling options to both the E and L-mounts, promising to deliver top-notch performance without breaking the bank the way Sony’s GM lenses or Leica’s L-mount lenses are notorious for doing.

The first of two Art lenses designed specifically for full-frame mirrorless (instead of being adapted from its DSLR designs), the Sigma 14-24mm f/2.8 DG DN Art is an ultra-wide angle zoom that’s being described as “the definitive lens for astrophotography.”
Inside, the lens uses 11 rounded aperture blades and an optical construction of 18 lens elements in 13 groups, including one FLD element, five SLD elements, and three aspherical elements to suppress chromatic aberration and reduce distortion. Together, these optics promise “mind-blowing resolution.”
The lens also features a newly-designed Nano Porous Coating (NPC) that will help reduce flare and maintain contrast even in heavy backlighting, a dust- and splash-proof housing, and a built-in rear-filter holder with a fall prevention lock.

The second Art lens of the bunch is the ultra-fast new Sigma 35mm f/1.2 DG DN: Sigma’s first ever f/1.2 lens and the first f/1.2 aperture lens for the full-frame Sony E-mount and L-mount systems.
The 35mm f/1.2 Art uses an optical construction of 17 elements in 12 groups, including three SLD elements and three aspherical lenses, one of which is a double-sided aspherical lens. As with the 14-24mm lens, the optics promise “overwhelming resolution” that Sigma claims can comfortably resolve over 50MP. And since this lens is going to be a bokeh monster at f/1.2, it also uses an 11-blade diaphragm with rounded aperture blades.
Finally, since autofocus at f/1.2 can be a beast, even at 35mm, the lens uses a large Hyper Sonic Motor (HSM) motor and a focus-by-wire system that promises precise control when manual focusing.

Sigma 45mm f/2.8 DG DN Contemporary
Finally, the last lens of the bunch is the Sigma 45mm f/2.8 DG DN Contemporary—the most affordable lens released today, as it’s not part of Sigma’s “ultimate performance” Art lineup. It’s designed to be a more affordable entry into the new full-frame mirrorless lineup of Sigma lenses, balancing “easy-to-carry size and high optical performance” in a retro-inspired design with a classic aperture ring “with the right click feeling.”
The more portable lens uses a 7-blade aperture diaphragm and an optical design of 8 elements in 7 groups. No fancy lens elements in this one, but it is still dust- and splash-proof, and with a minimum focusing distance of just 24cm (9.4 inches) it should make for a very versatile walk-around lens.

This is likely just the beginning for Sigma in the full-frame mirrorless space. As Sigma writes in their press release:
[We] will develop interchangeable lenses with unprecedented specifications and performance by designs that benefit from the short flange focal length feature of mirrorless cameras while retaining the concepts of “Contemporary,” “Art,” and “Sports.”
As Sony’s full-frame E-mount cameras continue to gain market share, Panasonic’s L-mount cameras make waves, and Sigma’s own pocket-sized Sigma fp hits the market this fall, there’s plenty of reason to develop more affordable, high-performance glass for full-frame mirrorless.
Speaking of which, while the brand offered no official confirmation, rumors indicate that these lenses will be released for Canon RF and Nikon Z mounts as well.
