Explore Versatile Photography and Videography with the Sigma 18-50mm f/2.8 DC DN Contemporary Lens

The Sigma 18-50mm f/2.8 DC DN Contemporary Lens, available in Leica L-mount, is a versatile option suitable for a wide range of photography and videography applications. With its full-frame equivalent zoom range of 27-75mm and constant aperture of f/2.8, it's ideal for capturing landscapes, portraits, street scenes, architecture, and events. The lens design incorporates three high-precision glass-molded aspherical elements and a special low dispersion element, ensuring excellent optical quality without excessive weight. Its fast and quiet autofocus, facilitated by a stepping motor, makes it particularly useful for video shooting and capturing fast-moving subjects. With a minimum focusing distance of just 4.8 inches, it's also capable of macro-style close-up photography. Additionally, the lens features a rounded seven-blade diaphragm, delivering pleasing bokeh for enhanced creativity.

  • Standard zoom lens is designed for APS-C-format Leica L-mount cameras and provides a 35mm equivalent focal length range of 27-75mm.
  • Constant f/2.8 maximum aperture is well-suited for working in low-light conditions and provides greater control over the focus position when using shallow depth of field techniques.
  • Three high-precision glass-molded aspherical elements are used to help limit distortion and spherical aberrations and contribute to greater overall sharpness and accurate rendering.
  • Special Low Dispersion (SLD) element reduces chromatic aberrations and colour fringing.
  • Super Multi-Layer Coating minimizes flare and ghosting for improved contrast and colour accuracy when working in strong lighting conditions.
  • In-camera aberration correction further eliminates optical imperfections such as distortion and vignetting.
  • Stepping motor with nearly silent autofocus that makes it perfectly suited to a range of photographic applications, including shooting in quiet environments, recording videos, and capturing fast-moving subjects.
  • Minimum focusing distance of 4.8" and a 1:2.8 maximum magnification ratio benefits working with close-up subjects.
  • Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
  • Compatible with Sigma UD-11 USB Dock for Leica L.
