Rumor site L Rumors, having sourced the information from Nokishita, posted the specification of a new 24mm f/3.5 DG DN lens.In fact, it looks to be one of four new optics to be announced on 1 December, when Sigma’s event will reveal a new series of DN lenses dedicated to mirrorless interchangeable-lens cameras.
A screenshot posted by L-rumors.com of what looks like a presentation slide shows a 35mm F2 DG DN, a 65mm F2 DG DN, a 24mm F3.5 DG DN and a 45mm F2.8 DG DN.
And another screenshot in the same L-rumors post reveals more details about the 24mm f/3.5 DG DN. Its optical path comprises 10 elements in 8 groups, with one special low-dispersion glass and three aspherical lenses, with a super multi-layer coating.
Autofocus is delivered via stepping motor and is compatible with high-speed camera AF systems, and the new optic is compatible with lens-based optical correction (only on supported cameras, and the corrections available may depend on the camera model).
Externally, the lens features an aperture ring, a focus mode switch and the mount’s structure is dust-proof and splash-proof. A metal lens hood and magnetic lens cap are supplied.
The new lens will be ideal for a variety of uses including landscapes, travel, weddings and events, creative, family and specialty applications.
