See below for the features / benefits and specifications of the Sigma 12mm f/1.4 DC | Contemporary Lens available to purchase online in multiple configurations at Icon Cameras.
Ultra-wide-angle prime (12 mm) with a very bright f/1.4 aperture — excellent for low-light, astrophotography, night skies, milky way, interiors.
Widest 12mm F1.4 among APS-C AF interchangeable lenses as of its release — giving a very expansive field of view with high brightness.
Lightweight & compact design: despite being a fast, wide prime, it remains portable and suitable for travel, vlog, landscape, video work.
Superior optical correction: uses double-sided aspheric elements and SLD glass to reduce aberrations (coma, chromatic, edge softness) even at wide open.
Good control features: aperture ring (in some mounts), minimal focus breathing for smoother video focus pulls.
Dust- and splash-resistant body; water- and oil-repellent front coating to resist fingerprints, moisture.

This lens uses a 62mm front filter thread. The options below match that size and use a screw-in mount. Choose UV for protection, CPL for reflections, or ND/VND for bright-light video and long exposures. Diffusion filters create a softer look. Avoid stacking filters on wide-angle lenses.
