Sigma 12mm f/1.4 DC Contemporary Overview

Lightest Lens in Contemporary Prime Series
Capture from a wide-angle perspective with the portable and fast-focusing 12mm f/1.4 DC Contemporary Lens from Sigma, which is designed for APS-C format Canon RF-mount mirrorless cameras. Providing a 19.2mm full-frame equivalent focal length, this lens offers a view that includes your entire scene, making it optimal for landscape, street, and indoor photography as well as vlogging.

Optical Construction
Three double-sided aspherical elements contribute to the lens's compact build and limit distortion while also improving overall image sharpness.

Two special low dispersion (SLD) elements reduce color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy.

Features 14 lens elements in 12 groups.

Ultra-Compact Design
The 12mm f/1.4 DC achieves the lightest weight of Sigma's f/1.4 DC Contemporary prime series of lenses, making it an excellent option for handheld video and travel photography. Additionally, it features a 20% shorter length than the previous Sigma 16mm f/1.4 DC DN lens, allowing it to easily fit in most bags.
Additional Highlights
  • Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
  • Dust- and splash-resistant lens structure with sealing prevents water and dust from entering inside the lens, increasing durability during outdoor shooting.
  • Water- and oil-repellent coating to the front lens element prevents droplets and fingerprints from accumulating.
  • Control ring for quick, convenient settings adjustment.
  • 62mm filter thread for wide compatibility with lens accessories.

1st Time Northern Lights - Worked Great (with Canon R7)

Purchased this lens to go with my Cannon R7 just before our March (26) trip to Fairbanks Alaska. With the crop sensor - I wanted to go wide (12*1.6= 19 full frame). This is my 2nd attempt to get some good Northern Light photos, 1st with this lens. This combo (with some practice - new to this) worked well for me. I was very happy with the photos I was able to take. There is a learning curve to this type of photography for sure. I have many, many, photos to play with in Light Room. Will use for other things, but so far very happy with this combo.
