Product Description

Sigma 12mm f/1.4 DC Contemporary Lens (Canon RF-Mount)

Compact, Wide, and Fast
The lightest model in Sigma’s f/1.4 DC Contemporary prime lineup, the 12mm f/1.4 DC is designed for APS-C format Canon RF-mount mirrorless cameras. Delivering an 18mm equivalent focal length, it captures an expansive field of view, making it ideal for landscapes, street scenes, interiors, and vlogging. Its bright f/1.4 aperture enables impressive low-light performance and shallow depth of field, while the stepping AF motor ensures fast, accurate, and near-silent autofocus with minimal focus breathing.
