Is this lens good for astrophotography?

Yes. Its F1.4 aperture and coma suppression are aimed squarely at night skies, and the rear filter holder takes gel filters for light-pollution tuning.

How does it compare with the older DSLR 24mm F1.4 Art?

The DG DN version is designed for mirrorless, adds a front filter thread, a rear filter holder and a Manual Focus Lock switch, and is lighter than the SLR model.

Does it fit full-frame Sony cameras?

It is made for Sony E-mount and covers full frame. It also mounts on APS-C E-mount bodies, where it behaves like a 36mm equivalent.

Can I use screw-on filters?

Yes, it has a front filter thread, and a rear holder accepts sheet filters for setups where a front filter is impractical.

No. It relies on the camera body's stabilization, so pair it with an IBIS-equipped body for handheld low-light work.

The lens comes with front and rear caps, a lens hood and a case.

What reviewers say

Owners and reviewers praise the lens for sharp, well-corrected images even at F1.4 and for its coma control on stars. Most criticism centers on its size and weight and on vignetting that needs stopping down to clear.

What people mention

SharpnessPraisedReviewers say it resolves fine detail well even wide open and improves further stopped down.
Coma controlPraisedAstro shooters report tight, round stars toward the corners at F1.4.
Size and weightCriticisedOwners call it big and heavy for a wide prime, which matters on long hikes or gimbals.
VignettingMixedCorner darkening is visible at F1.4 and mostly clears by F2.8.
Focus breathingCriticisedVideographers note the field of view shifts noticeably when focusing.
BuildPraisedThe metal barrel, weather sealing and aperture ring draw positive comments.

About the Sigma 24mm F1.4 DG DN Art Lens

The Sigma 24mm F1.4 DG DN Art is a wide-angle prime lens for Sony E-mount mirrorless cameras. It has a maximum aperture of F1.4 and a 24mm focal length. It is made for situations from indoor snapshots and travel to architecture, landscape and astrophotography.

The optical design uses 17 elements in 14 groups, including two FLD, one SLD and four aspherical elements. It is designed to suppress aberrations such as sagittal coma flare, ghosting and flare. Super Multi-Layer Coating and Nano Porous Coating help it render clearly in backlit conditions and near maximum aperture.

The lens has a dust- and splash-resistant structure and a water- and oil-repellent coating on the front element. It can be used in light rain but is not waterproof. A stepping motor drives fast, silent autofocus. A Manual Focus Lock (MFL) switch disables the focus ring so a manually set focus cannot be moved by accident. It takes front filters and also has a rear filter holder, so filters can be combined.
