Ultra-Compact Design
The 12mm f/1.4 DC achieves the lightest weight of Sigma's f/1.4 DC Contemporary prime series of lenses, making it an excellent option for handheld video and travel photography. Additionally, it features a 20% shorter length than the previous Sigma 16mm f/1.4 DC DN lens, allowing it to easily fit in most bags.

Dust- and splash-resistant lens structure with sealing prevents water and dust from entering inside the lens, increasing durability during outdoor shooting.
Water- and oil-repellent coating to the front lens element prevents droplets and fingerprints from accumulating.
Aperture ring for quick, convenient settings adjustment.
