Sigma has announced the new 24-70mm f/2.8 DG DN Art lens for full-frame mirrorless cameras. It’ll be available at launch for the E-mount by Sony and the L-mount by the Leica/Panasonic/Sigma L-Mount Alliance.
The new lens is the second DN Art lens designed for full-frame mirrorless cameras, following the 14-24mm f/2.8 DG DN Art. Sigma says the new 24-70mm f/2.8 offers the best optical performance of its class thanks to a sophisticated optical design.
While remaining smaller and lighter than its DSLR counterparts, the new Sigma 24-70mm f/2.8 DG DN Art achieves a uniform high resolution from the center of the frame to the edges throughout the entire zoom range.
“By employing three aspheric lenses, this zoom lens thoroughly subdues aberrations such as axial chromatic aberration or sagittal coma aberrations, which are difficult to correct in post-processing, tailors the resolution and achieves uniformity and superior optical performance from the center to the periphery throughout the zoom range,” Sigma says.
On the front of the lens is Sigma’s Super Multi-Layer Coating and Nano Porous Coating, the latter of which helps the lens achieve high contrast and clear images. The coatings help reduce flare and ghosting when shooting with strong incident light.
Build-wise, the lens is both dust- and splash-proof, and there’s a zoom lock switch on the body to prevent the lens barrel from extending when you don’t want it to.
Other features and specs of the lens include maximum magnifications of 1:2.9 (wide) and 1:4.5 (tele), a minimum focusing distance of 7in/18cm (on the wide end), a locking lens hood, an 11-bladed rounded diaphragm for smooth bokeh, a rugged brass bayonet mount, and Japanese manufacturing.
The Sigma 24-70mm f/2.8 DG DN Art will be available in E and L mounts starting in mid-November 2019. Pricing has yet to be announced.
