Sigma continues to shake up the lens world by giving photographer's another option when it comes to high quality optics for their camera bodies. The Japanese company announced a trio of new lenses for Sony full-frame E-mount as well as the Panasonic/Leica/Sigma alliance L-mount cameras with the 35mm F1.2 DG DN Art, 14-24mm F2.8 DG DN Art and 45mm F2.8 DG DN Contemporary.

Sigma 14-24mm F2.8 DG DN Art

Sigma's latest wide-angle zoom is what they call the "definitive lens for astrophotography", featuring 18 lens elements in 13 groups and an 11-blade rounded aperture. Of the 18 elements, five are SLD, three are aspherical and one is FLD for eliminating chromatic aberrations and lens distortion. Unlike the majority of Sigma's mirrorless lenses that are adaptations of full-frame DSLR models, the 14-24mm is one of the first two that's been designed from the ground up for full-frame mirrorless cameras.

The Sigma 14-24mm F2.8 DG DN Art is expected to be available in August at a MSRP of $1899.95.

Sigma 35mm F1.2 DG DN Art

With an aperture of F1.2, the Sigma 35mm F1.2 DG DN Art has the largest diameter aperture for any of their prime lenses. It's also the first F1.2 lens for either Sony E-mount or L-mount cameras. 

Made from 17 elements in 12 groups (including three SLD, three aspherical and one double-sided aspherical), Sigma claims the 35mm F1.2 is one of their best, capable of "overwhelming" resolution and detail. They also expect it to have excellent bokeh with an 11-blade rounded aperture.

The Sigma 35mm F1.2 DG DN Art is expected to be available later in July at a MSRP of $1649.95.

Sigma 45mm F2.8 DG DN Contemporary

The Sigma 45mm F2.8 DG DN Contemporary is designed with portability in mind without compromising optical performance. Sigma says this lens is best for a standard, every day lens that's capable in many different situations. 

Focus is courtesy of a high-speed stepping motor which supports Face/Eye Detection autofocus and video autofocus. The 45mm F2.8 contains 8 elements in 7 groups, has a 7 blade, rounded aperture and features a classic retro-inspired design.

The Sigma 45mm F2.8 DG DN Contemporary is expected to be available later in July at a MSRP of $699.95.
