Sigma 14-24mm f/2.8 DG DN Art lens announced for full-frame mirrorless cameras. The Art lens will be released in August for Panasonic / Leica L-mount and Sony E-mount.
The company calls it the ‘definitive lens for astrophotography’ and emphasizes its ‘outstanding’ resolution to the edges of the frame, achieved in part thanks to the inclusion of low dispersion elements and Sigma’s Nano Porous Coating (NPC).
The lens is splash and dustproof, and features a rear filter holder. The aperture diaphragm uses 11 rounded blades, and the lens weighs 28 oz / 795g. Shipping will start in late August 2019 and US Price would be around $1,300.
