The Sigma 24mm F1.4 DG DN Art for L-Mount is a fast full-frame wide-angle prime. Sigma designed it to meet the demands of astrophotography while keeping it compact for an F1.4 lens, and at 520g it balances well on a Lumix S5II, Sigma BF or Leica SL3.
Optical design
There are 17 elements in 14 groups, including two FLD, one SLD and four aspherical elements. Sigma tuned the design for sharp, point-like stars across the frame at F1.4.
Made for night shooting
A lens heater retainer holds a dew strap in place, and there is a rear filter holder for sheet filters alongside the 72mm front thread.
Controls
There is an aperture ring with a click switch and a lock, an assignable AFL button and a manual focus lock switch. The petal hood locks onto the lens.
Built for the outdoors
The body is dust- and splash-resistant, and the front element has a water- and oil-repellent coating.
Who it's for
This is for astro, landscape, event and wedding photographers who want a fast wide prime that is still a sensible size. The Sigma 24mm F3.5 DG DN is the pocketable alternative with 1:2 close focus, and the Sigma 35mm F1.4 DG II gives a more natural standard view.
