Ronkonkoma, NY—Sigma added three Global Vision Art lenses, all with full-time manual focus override and support for Canon, Nikon and Sigma mounts. The Nikon mounts feature the new electromagnetic diaphragm. The Art lenses are compatible with Sigma’s MC-11 Sony E-mount converter. Pricing and available are yet to be announced for the 14mm and 24–70mm lenses.
Sigma 14mm f/1.8 DG HSM Art
Marketed as “the world’s first 1.8 wide-angle lens,” the ultrawide prime is engineered to produce virtually no distortion, flare or ghosting. The lens offers full-frame 35mm coverage and a 14mm focal length for an ultrawide angle of view. Sigma says it’s built for outstanding image quality from center to edge and features the largest glass mold (80mm) in the industry. Three lens elements are made with FLD (“F” low dispersion) glass, equivalent to calcium fluorite, and four SLD (special low dispersion) glass elements, to reduce chromatic aberration. The lens also has a fast, efficient AF system.
The large-diameter lens has a 10.6-inch minimum focus distance at 14mm. It combines the extremely deep depth of field that comes from an ultrawide angle of view with the extremely shallow depth of field that comes from f/1.8 brightness. As a result, it can capture close-up shots with expansive backgrounds.
Sigma 135mm f/1.8 DG HSM Art
For full-frame cameras, this is Sigma’s premier midrange telephoto prime lens. Suitable for events such as indoor sports and press events, the 1.8 F-stop delivers greater shallow depth of field and isolation of subjects. The compression effect makes it equally suited for up-close and full-length portraits.
In addition, the large diameter with f/1.8 brightness provides a dramatic bokeh effect. Furthermore, a larger hypersonic motor (HSM) provides ample torque to the focus group for optimal speed.
Other features include: a focus limiter; a 34.4-inch minimum focus distance; a 9-blade rounded diaphragm; and dust- as well as splashproof construction.
Sigma 24–70mm f/2.8 DG HSM OS Art
Employing Sigma’s new OS (optical stabilizer) as well as fast AF system, this updated 24–70mm f/2.8 Art lens covers a range of shooting scenarios. Three SLD glass elements and four aspherical elements work to reduce chromatic aberration. Furthermore, the aspherical elements use Sigma’s thicker center glass design and polishing process, to deliver bokeh effects.
The purpose-built structure also has a new metal barrel for durability with Thermally Stable Composite internal moving components designed to resist thermal contraction and expansion in all temperatures. Features also include a hypersonic motor with 1.3x the torque of its predecessor for fast AF; and dust/splashproof construction. sigmaphoto.com
