What We Like
+Ultra-wide 12mm focal length is world's first F1.4 prime for APS-C at this focal length, ideal for landscapes, astrophotography, and vlogging
+Exceptionally compact and lightweight at 225-250g, making it highly portable for travel and outdoor use
+F1.4 aperture enables impressive low-light performance and low ISO capability in challenging lighting conditions
+First Sigma APS-C Contemporary prime with aperture ring, providing manual control and professional feel similar to Art series
+Minimal focus breathing and suppressed flare/ghosting deliver smooth video pulls and clean images in all conditions
+Quality construction includes dust and splash resistance with premium Thermally Stable Composite exterior
Worth Knowing
−Barrel distortion is noticeable, though correctable in post-processing and typical for ultra-wide lenses
−Softer corner performance at F1.4, though improves significantly when stopped down to F2 and beyond
−No AF/MF switch means manual focus must be engaged through camera menus
−Moderate vignetting at F1.4 aperture, though controlled better than competing lenses

Read our notes on general
The Sigma 12mm F1.4 DC Contemporary is the world's first lens to achieve a 12mm focal length with F1.4 aperture for APS-C cameras, capturing an ultra-wide 18mm-equivalent field of view ideal for nighttime and landscape photography. Its compact 69.4mm length and 225g weight provide excellent portability while introducing an aperture ring—a first for Sigma's Contemporary prime series. Praised for optical performance and compact design, the lens features minor trade-offs like barrel distortion and softer corners, yet competes well against other offerings.
