Fifteen elements in 11 groups. Nine rounded aperture blades. The 62mm filter thread. At 350g. Minimum focus distance of 0.24m. Stepping motor for quiet AF. f/2 maximum aperture. Full-frame coverage (DG = full-frame grade). Sony FE mount.
The DG DN designation confirms mirrorless-native full-frame design: DG (full-frame Digital Grade) + DN (Digital Neo, mirrorless). The f/2 aperture at 24mm provides one stop more light than f/2.8 competitors at the same focal length, improving low-light performance and selective focus at the wide end. At 350g the lens is notably compact for a full-frame fast wide prime.
On the used market the Sigma 24mm f/2 DG DN Contemporary is affordable as a compact Sony FE fast wide prime. Condition checks: AF response, 62mm front element for marks. Full-frame Sony FE. Compatible with all Sony FE-mount full-frame and APS-C E-mount bodies.
