Sigma has announced the Sigma 16-28mm F2.8 DG DN | C, a new full-frame ultra-wide zoom lens which will be available from 17th June with the L-mount for Sigma, Leica and Panasonic L-mount cameras, and the Sony E-mount.
Sigma has employed its latest optical design technology to ensure that the 16-28mm F2.8 DG DN | C is compact (just 100.6mm long) yet capable of delivering high image quality. It is constructed from 16 elements arranged in 11 groups, with 5 FLD and 4 aspherical elements. The FLD (F low dispersion) elements are said the deliver the same quality as fluorite elements without the expense and fragility.
Sigma’s Super Multi-Layer Coating has also been applied to reduce flare and ghosting.
Thanks to Sigma’s use of Thermally Stable Composite (TSC), a polycarbonate with a thermal contraction rate similar to that of aluminium, the lens weighs just 450g. Its zoom and focusing mechanisms are also internal so that it stays the same length throughout its zoom and focus range, helping to maintain balance in the hand or on a gimbal.
Focusing is handled by a stepping motor and there’s a focus mode switch on the barrel.
