Sigma 28-70mm f/2.8 DG DN Contemporary Lens for Sony E-Mount

The Sigma 28-70mm f/2.8 DG DN Contemporary Lens designed for Sony E-Mount is a versatile zoom lens covering a wide-angle to portrait-length range, distinguished by its constant f/2.8 maximum aperture. This design is well-suited for working in various lighting conditions while providing precise control over depth of field. Notably more lightweight and compact compared to similar 24-70mm lenses, its optical construction includes two FLD and two SLD low-dispersion elements, along with three aspherical elements, effectively minimizing a range of aberrations. The result is high sharpness, enhanced clarity, and improved colour accuracy.

With just one lightweight focusing element, the lens keeps its autofocus (AF) unit compact. Combined with a quiet and fast stepping motor, this configuration ensures responsive and nearly silent autofocus performance. This makes it an excellent choice for filmmakers seeking a high-performance, lightweight lens that is easy to handle and works seamlessly with gimbals or other accessories, contributing to an optimal filming experience.

Each optical surface features Super Multi-Layer and Nano Porous coatings to improve contrast and colour rendering by suppressing lens flare and ghosting for optimal light transmission, and an added water- and oil-repellent coating on the front optic helps keep the lens free from smudges and droplets. The weather-sealed design benefits working in trying environmental conditions, and a nine-blade rounded diaphragm contributes a pleasing bokeh quality when using wider apertures.

  • Standard zoom for full-frame E-mount mirrorless cameras
  • 42-105mm equivalent focal length when used on an APS-C camera
  • Constant f/2.8 maximum aperture for Low light use and depth-of-field control
  • Two F Low Dispersion (FLD) and two Special Low Dispersion (SLD) elements reduce chromatic aberrations and colour fringing
  • Three aspherical elements control spherical aberrations and distortion
  • Both Super Multi-Layer and Nano Porous coatings minimize lens flare and ghosting and produce contrast-rich and colour-neutral imagery
  • Integrated stepping motor and optimized AF algorithm provides quick and quiet autofocus
  • 28mm minimum focus distance: 7.5", 1:3.3 magnification
  • 70mm minimum focus distance: 15", 1:4.6 magnification
  • Rounded nine-blade diaphragm for a pleasing bokeh quality
  • Brass bayonet for mounting accuracy and rigidity
  • Rubber sealing for dust- and splash-resistance
