Sigma 16-28mm f/2.8 DG DN Contemporary Lens for Leica L

The Sigma 16-28mm f/2.8 DG DN Contemporary Lens is a compact and high-performance ultrawide zoom lens designed to enhance a photographer's toolkit by offering a versatile array of focal lengths in a lightweight and portable format, all while maintaining exceptional optical quality. Its constant f/2.8 aperture facilitates the use of faster shutter speeds in low-light conditions and is particularly advantageous for close-up photography due to its shallow depth of field.

This lens incorporates a sophisticated configuration of specialized aspherical and low-dispersion glass elements, effectively minimizing chromatic aberrations to enhance clarity and color fidelity. Additionally, Super Multi-Layer and Nano Porous Coatings have been applied to optimize contrast and color reproduction by mitigating lens flare and ghosting in challenging lighting situations. The internal zoom and focus mechanism ensures that the lens dimensions remain consistent across the entire zoom range and at all focus distances. This design characteristic results in minimal balance point shift and a fixed front element, making it an excellent choice for videography, travel, and landscape photography.

• Constant f/2.8 maximum aperture is well-suited for working in available lighting conditions.
  
  
• Two large-diameter aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.
  
  
• Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
  
  
• 72mm front filter thread allows for the use of common screw-in filters instead of specialized setups.
  
  
• A stepping AF motor benefits both photographers and videographers with its fast, precise, and near-silent performance. Full-time manual focus control can also be selected.
  
  
• Weather-resistant construction with a brass bayonet that affords improved mounting accuracy and rigidity.
