For Canon EOS R APS-C users, the Sigma 12mm F1.4 DC | Contemporary provides an equivalent focal length of 19mm, delivering sweeping wide-angle views with the brightness of F1.4. This makes it especially useful for nightscapes, architecture, and low-light shooting where detail and clarity are essential. Whether capturing dramatic city scenes or expansive landscapes, the lens combines creative potential with practical usability.

The advanced design features three aspherical and two SLD elements, ensuring sharp, clear rendering with minimal distortion or aberrations. Even in challenging conditions, such as shooting stars against a dark sky, sagittal coma flare is well-controlled, so point light sources remain precise. Sigma’s coatings further reduce flare and ghosting, maintaining contrast and colour fidelity in backlit situations.

Weighing only 225g and measuring just under 70mm in length, the lens matches the compact, lightweight nature of Canon’s RF-S cameras such as the EOS R7, R10, and R50. It’s small enough to be a daily companion for travel, street photography, or handheld video, yet powerful enough to deliver professional-quality results.

The RF-S version replaces the aperture ring with a programmable control ring, allowing you to assign functions such as aperture, ISO, or exposure compensation directly to the lens. Combined with a fast and quiet stepping motor, this makes the lens ideal for hybrid creators who switch between photography and video. Minimal focus breathing ensures smooth transitions when focusing during video recording, while the dust- and splash-resistant structure allows reliable use outdoors.
