Four Sigma lenses

Posted on Updated on

sigmaSigma has announced four new lenses, three in its Art category, one in its Contemporary category: 14 mm f/1.8 DG HSM Art, 135 mm f/1.8 DG HSM Art, 24-70 mm f/2.8 DG HSM OS Art, 100-400 mm f/5-6.3 DG HSM OS Contemporary.

Sigma says the 14 mm lens incorporates the same aspherical element as the company’s 12-24 mm f/4 Art. Boasting outstanding image quality from centre to edge, the 14 mm lens features the largest glass mold (80 mm) in the industry, notes Sigma, offering an ultra-wide prime with virtually no distortion, flare or ghosting. Three lens elements are made with FLD (“F” Low Dispersion) glass, which is equivalent to calcium fluorite in performance, and four SLD (Special Low Dispersion) glass elements, which reduce chromatic aberration. The company also touts the lens’ fast and efficient AF system. Minimum focusing distance is 10.6 inches at 14 mm.

The 135 mm lens boasts outstanding sharpness and great IQ from edge to edge, a new large hyper sonic motor (HSM) providing ample torque to the focus group for optimal speed while the acceleration sensor detects the position of the lens for compensation, producing faster and more responsive AF. The lens is equipped with a focus limiter.

Featuring a brand new OS and highly efficient and fast AF system, the revamped 24-70 mm includes three SLD (Special Low Dispersion) glass elements and four aspherical elements to reduce chromatic aberration. The aspherical elements use Sigma’s thicker centre glass design and highly precise polishing process. The lens boasts a new metal barrel for optimal durability with TSC composite internal moving components designed to resist thermal contraction and expansion.

The 100-400 mm Contemporary zoom lens is said to offer great IQ and usability with its lightweight, compact, dust- and splash-proof design. Equipped with new OS and AF, the lens claims exceptional performance at lower shutter speeds, and also features a macro function (1:3.8 ratio), and push/pull focal zooming.

The four Sigma lenses support Canon, Nikon and Sigma mounts and works with Sigma’s MC-11 Sony E-mount converter. The Nikon mounts feature a new electromagnetic diaphragm.

The lenses can be updated with the latest lens software from a workstation or laptop using the Sigma Optimization Pro software and Sigma USB Dock (sold separately). The new Sigma lenses are also available for mount conversion services.

Canadian availability and pricing have not yet been announced.
