The Sigma 12mm f/1.4 DC Contemporary lens stands as a revolutionary ultra-wide-angle optic for APS-C mirrorless systems, offering an unprecedented combination of field of view and extreme brightness. This lens has been designed to meet the needs of professionals working in landscape, architectural, and astrophotography, where the maximum f/1.4 aperture allows for capturing detailed images with reduced digital noise even in extremely low light conditions. The sophisticated optical construction integrates low-dispersion glass elements and high-precision aspherical lenses that work in synergy to drastically correct typical distortions of such wide focal lengths and chromatic aberrations, ensuring crystal-clear resolution from the center to the edges of the frame. Despite its high-level optical performance, the lens maintains the Contemporary line's philosophy, offering a compact and lightweight body that does not unbalance the camera during use on gimbals or tripods. The autofocus system, driven by a fast and silent stepping motor, ensures smooth subject tracking in both photography and video, while the weather-sealed structure protects the lenses from dust and splashes, making this 12mm a reliable tool for the most demanding outdoor shooting sessions.
