Lightweight Ultra-Wide Prime for APS-C Mirrorless

Designed for APS-C format Canon RF-mount cameras, the Sigma 12mm f/1.4 DC Contemporary lens delivers a dramatic ultra-wide 18mm equivalent field of view in a highly portable form factor. Its bright f/1.4 maximum aperture provides impressive low-light performance and allows for smooth background separation, making it well-suited for landscapes, city scenes, interiors, and vlogging. A stepping AF motor ensures fast, accurate autofocus with minimal focus breathing, ideal for both stills and video work.

Optical Performance

• Three double-sided aspherical elements minimize distortion and enhance edge-to-edge sharpness.
• Two special low dispersion (SLD) elements reduce chromatic aberrations and color fringing for improved clarity and accuracy.
• Complex optical design with 14 elements arranged in 12 groups for refined image quality.

Ultra-Compact Build

Achieving the lightest weight in Sigma’s f/1.4 DC Contemporary prime lineup, the 12mm f/1.4 is 20% shorter than the Sigma 16mm f/1.4 DC DN, making it easy to pack and carry for handheld shooting, travel, or on-the-go content creation.

Additional Features

• Rounded nine-blade diaphragm delivers smooth, natural-looking bokeh.
• Dust- and splash-resistant design with sealing for added durability in outdoor conditions.
• Front element features a water- and oil-repellent coating to reduce smudges and droplets.
• Manual aperture ring for quick, intuitive adjustments.
