Sigma 50mm f/1.4 DG DN Art Lens for Leica L-Mount

Crafted for Leica L-mount mirrorless cameras, the Sigma 50mm f/1.4 DG DN Art Lens combines sophisticated optical performance with high-speed autofocus capabilities. Ideal for portraiture, landscapes, and versatile shooting scenarios, its 50mm focal length is complemented by a bright f/1.4 maximum aperture, providing precise control over depth of field.

Employing the latest optical design technology, this lens integrates 14 elements in 11 groups, featuring three aspherical lenses and one SLD glass element. The result is effective suppression of various aberrations such as astigmatism and field curvature that cannot be corrected in-camera. Beyond its optical excellence, the lens delivers swift and quiet focusing, ensuring excellent tracking performance. This versatility makes it suitable for a range of situations, including low-light environments, capturing moving subjects, and videography.

• Prime standard-length lens designed for full-frame Leica L-mount mirrorless cameras, however, can also be used on APS-C models where it provides a 75mm equivalent focal length.
• Bright f/1.4 maximum aperture offers control over depth of field and suits working in low-light conditions.
• Newly designed HLA (High-response Linear Actuator) focusing motor provides unprecedented high-speed, high-precision, and quiet AF.
• Based on the latest optical design technology, the lens incorporates 14 elements in 11 groups, with 3 aspherical lenses and 1 SLD glass element. The lens effectively suppresses various aberrations such as astigmatism and field curvature, which cannot be corrected in-camera.
