Sigma 35mm F1.2 DG DN, L-Mount

The "Art product line in the mirrorless camera era" aims for performance with a focal length of 35mm and also achieves a maximum aperture of F1.2. Three SLD glass elements and three aspherical lenses including a double-sided aspherical lens are optimally arranged in a lens construction of 17 elements in 12 groups. In addition to its optical design that takes advantage of the short edition dimension characteristic, it effectively employs the in-camera correction function to correct distortion and vignetting. Various aberrations that are difficult to correct by post-processing, such as sagittal coma, are fully corrected by the combination of optical design technologies developed by , achieving a stunning resolution of over 50 million pixels.

Operability in a wide range of shooting situations, both still and video. With a large-diameter F1.2 lens, comfortable autofocus photography is achieved by the large Hyper-Sonic Motor (HSM), which achieves the desired rotational force required to control the focus lens group. For manual photography, the focus ring driven by the focus-by-wire system responds to fine adjustments made by the photographer with the optimized rotational force setting. In addition, the aperture ring is equipped with an anti-click function that eliminates clicks and allows for transition-free operation that is especially useful when shooting video.

Comprehensive feature set ensures user confidence even under difficult conditions. The AFL button, which can be assigned with various functions, expands the working range of the lens. In addition, the lens features a dustproof and splashproof design, as well as a water- and oil-repellent coating on the front lens, which further supports shooting in various environments.
