Sigma has officially announced the two newest lenses in their Global Vision Lenses lineup for Sony E Mount and Leica L mount. As expected, they’re the Sigma 20mm f/1.4 DG DN Art and the Sigma 24mm f/1.4 DG DN Art series lenses. Both lenses are primarily aimed at astrophotographers, although the 24mm is also targeted towards general photography use.
Both lenses come with some features advantageous to astrophotographers, with the introduction of a manual focus lock and a rear filter holder as well as front filter threads. The 20mm f/1.4 DG DN also comes with a “Lens Heater Retailer” to “keep this useful astrophotography weather accessory firmly in place while in use”. The lenses were announced during today’s Sigma Stage event.
Being very bright wide aperture lenses with a wide angle of view, these two full-frame lenses are both squarely targeted toward astrophotographers. Rear filter holders help to prevent the fogging issues common with front filters as the sun goes down and the night starts to get cold, although both lenses feature filter threads on the front, too, making them equally ideal for landscape photographers who wish to use a square filter system with a holder.
