Sigma 50mm f/1.4 DG DN Art Lens | Leica L

The Sigma 50mm f/1.4 DG DN Art Lens, engineered for Leica L-mount mirrorless cameras, delivers exceptional optical performance alongside rapid autofocus capabilities. With a focal length of 50mm, it is perfectly suited for portrait photography, landscapes, and versatile shooting scenarios, featuring a bright maximum aperture of f/1.4 that facilitates control over shallow depth of field. Utilizing advanced optical design principles, the lens comprises 14 elements arranged in 11 groups, including three aspherical elements and one SLD glass component. This construction effectively mitigates various aberrations, such as astigmatism and field curvature, which are typically uncorrectable in-camera. Furthermore, the lens provides swift and silent focusing, along with outstanding tracking performance, making it suitable for diverse applications, 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.
  
  
• Equipped with a focus mode switch, an aperture ring click switch, an aperture ring lock switch to prevent unintended operation, and an AFL button to assign any function from the camera.
  
  
• Rounded 11-blade diaphragm contributes to a smooth and pleasing bokeh quality when employing selective focus techniques.
  
  
• Front lens element has been treated with a water- and oil-repellent coating to benefit working in harsh environmental conditions.
  
  
• Dust and splash-resistant construction with a brass bayonet mount for ensured accuracy and durability.
