Ronkonkoma, NY—Sigma is marketing its new 16mm f/1.4 DC DN | Contemporary lens as the “world’s first interchangeable lens for Sony E-mount mirrorless cameras in the APS-C format to offer a 24mm-equivalent focal length and f/1.4 brightness. Moreover, on Micro Four Thirds cameras, the lens provides a 32mm-equivalent focal length with the same f-number of 1.4.
Over the years, Sigma has developed a lineup of bright prime lenses ranging from wide-angle to telephoto. For mirrorless cameras, the company is developing a range of interchangeable lenses that feature a lightweight, compact package for daily shooting.
The new large-diameter, wide-angle lens reflects that lightweight, compact design. And, like all Sigma’s DN lenses for mirrorless cameras, it is engineered to deliver “superior performance covering the key focal lengths,” the company announced. In addition, it allows increased control over depth of field for selective focus control. With a rounded, 9-blade diaphragm, it also produces pleasing bokeh.
The new lens builds on the 30mm f/1.4 DC DN | Contemporary, which Sigma released in 2016 as the first in a new series of prime lenses for mirrorless cameras. Sharing its development concept with the 30mm f/1.4 DC DN | Contemporary, the new 16mm Contemporary features a lens structure with 16 elements in 13 groups.
The lens is engineered to effectively minimize optical aberrations. It is also built to offer crisp resolution at wide-open aperture and throughout the aperture range. It employs three FLD (fluorite equivalent) elements, two SLD (super-low dispersion) and two molded aspherical elements. And Sigma’s Super Multilayer coating aids in suppressing flare and ghosting.
In addition, its optical design and stepping motor are built to deliver smooth autofocus during video shooting. Furthermore, the mount features a special sealing for a dust- and splashproof design. The lens is also constructed using a Thermally Stable Composite (TSC) material for use in wide temperature variations.
The Sigma 16mm f/1.4 DC DN | Contemporary lens has a suggested retail price of $449. In addition, it comes in both Sony E and Micro Four Thirds mounts.
Sigma DC DN Lenses
Sigma lenses with DC in the name are designed for optimal performance on cameras with APS-C image sensors. When a DC lens is used with a camera with a full-frame image sensor, vignetting will occur. Photographers are advised to adjust image area settings for optimal image results.
Furthermore, Sigma lenses with DN in the name are designed for optimal performance on cameras with a short flange back distance. sigmaphoto.com
