Sigma’s New 12mm f/1.4 DC Lens

Sigma has added another fast APS-C prime to its lineup with the new 12mm f/1.4 DC | Contemporary. It’s now the widest autofocus f/1.4 prime available for mirrorless cameras in this format, giving photographers and videographers an ultra-wide option that’s still compact. The lens measures under 7cm in length, weighs 225g, and takes standard 62mm filters, so it’s a pretty small package considering how wide and fast it is.

The lens comes in Sony E, Fujifilm X, and Canon RF mounts, giving roughly an 18mm field of view on Sony and Fuji bodies and about 19mm on Canon APS-C cameras. Sigma has tailored the design a bit depending on the mount: the Sony and Fuji versions include both a manual aperture ring and a wide focus ring, while the Canon RF version instead gets Canon’s familiar control ring. All three have weather sealing and a coating on the front element to help keep out water and smudges. Autofocus is designed to be quick and quiet, and Sigma has worked to reduce focus breathing.

Inside, the optical design packs 14 elements in 12 groups, including aspherical and SLD glass to keep distortion and aberrations under control. Sigma also points to reduced sagittal coma flare, which is especially important for astrophotography. The lens can focus down to 17.2cm and it is designed to stay sharp even when shot wide open. The new 12mm f/1.4 DC | Contemporary will be available in early September for $629.
