SIGMA has been very busy. If you can tear yourself away from the SIGMA fp reveal video, you might be interested to know that the Japan-based imaging manufacturer has also bombarded us with information regarding a trio of optics from its Art and Contemporary ranges: an ultra-wide-angle zoom and two primes. Compatible with L-mount and Sony E-mount systems, here’s what we know about SIGMA’s first full-frame mirrorless exclusive lenses…

 

Sigma’s first L-mount announcement is a triple-header comprising two primes and an ultra-wide-angle zoom

 

Art 35mm f/1.2 DG DN

The pick of the bunch is arguably the Art 35mm f/1.2 DG DN. It’s currently the only full-frame mirrorless 35mm f/1.2 lens that’s capable of autofocusing in existence. The large-diameter lens is built from 17 elements in 12 groups, including three special low-dispersion elements and three aspherical elements (of which one is double-sided).

Autofocus is achieved via a large Hyper Sonic Motor that drives the focus lens group. For manual focus, the lens uses a focus-by-wire system. Videographers can make use of the aperture ring’s ‘de-click’ function. The lens also includes an AFL button, which can be customised to perform a variety of functions. Finally, the lens is safeguarded due to its splash and dustproof construction and the front lens’ water- and oil-repellent coating.

Art 14-24mm f/2.8 DG DN

Astro aficionados take note, SIGMA is calling its Art 14-24mm f/2.8 DG DN: “the ‘definitive lens for astrophotography.’” Night-time shots will definitely benefit from that fast f/2.8 aperture and we’re told to expect “outstanding” edge-to-edge resolution. The lens comprises one of SIGMA’s F low-dispersion elements, five special low-dispersion elements and three aspherical elements to help reduce chromatic aberration and coma flare.

SIGMA’s new Nano Porous Coating will also help to reduce flares and ghosting, which we’re told will cause “the reflectance to be lowered more than conventional anti-reflective coatings.” A stepping motor should provide high-speed and quiet autofocusing and an AFL button can be programmed to perform various functions. Finally, the lens is fitted with a rear filter holder that’s compatible with sheet-type rear filters. Just like the Art 35mm f/1.2, the lens is splash and dustproof, and features a water- and oil-repellent coating.

Contemporary 45mm f/2.8 DG DN

The final lens to talk about is the 45mm f/2.8 DG DN. It’s part of SIGMA’s Contemporary range and is by far the cheapest lens in the trio. The prime’s big selling point is its compact size, it measures just 64.0mm x 46.2mm and weighs just 215g. Bokeh is a big talking point, with SIGMA citing: “large bokeh in the front and rear of the subject”. However, that 45mm focal length will be useful in a variety of situations and SIGMA tells us to expect crisp images at narrower apertures too. If that wasn’t enough, the lens’ minimum focusing distance of 24cm makes close-up images very possible, and you can shoot with confidence thanks to its splash and dustproof construction.
