The Sigma 12mm f/1.4 DC Contemporary is an ultra-wide, fast prime made for APS-C mirrorless cameras. On a Sony E-mount body it gives an 18mm full-frame-equivalent view with a 99.6° angle of view, and its bright f/1.4 aperture makes it a natural fit for astrophotography, interiors, landscapes, vlogging and low-light street shooting.

Sharp Edge to Edge, Even Wide Open

14 elements in 12 groups, including 3 aspherical and 2 SLD (special low dispersion) elements, deliver crisp, high-contrast images from center to corner at f/1.4, while Sigma's coatings keep flare and ghosting under control.

Fast, Quiet Autofocus for Photo and Video

A stepping motor drives smooth, near-silent focusing with full support for face and eye detection, and minimal focus breathing keeps video focus pulls clean.

Small, Light and Weather-Ready

At just 225 g (7.9 oz) and 68 x 69.4 mm, it balances well on compact bodies and gimbals. A physical aperture ring gives direct exposure control, and the dust- and splash-resistant build with a water- and oil-repellent front element is ready for travel.
