Sigma 17-50mm f/2.8 EX DC HSM Overview

Characterized by its versatile zoom range and bright design, 17-50mm f/2.8 EX DC HSM from Sigma covers a wide-angle to portrait-length range and features a constant f/2.8 maximum aperture to excel in available light conditions. The optical design incorporates a pair of low dispersion elements along with a trio of aspherical elements to reduce a variety of aberrations and promote greater sharpness and clarity. A Super Multi-Layer Coating is also used to suppress flare and ghosting for improved contrast and color accuracy. Benefitting the optics, a Hyper Sonic Motor affords quick and quiet autofocus performance and the lens is distinguished by its sleek profile, making it an ideal lens for walkaround and travel shooting.

  • Standard zoom lens is designed for APS-C-format Sony A-mount cameras and provides a 25.5-75mm equivalent focal length range.
  • Constant f/2.8 maximum aperture is well-suited for working in low-light conditions and also provides greater control over the focus position when using shallow depth of field techniques.
  • Two F Low Dispersion (FLD) elements are featured in the optical design, and help to reduce color fringing and chromatic aberrations for improved clarity and color accuracy.
  • Three aspherical elements are used to help limit distortion and spherical aberrations and also contribute to greater overall sharpness and accurate rendering.
  • Super Multi-Layer Coating has been applied to individual elements to minimize flare and ghosting for improved contrast and color accuracy when working in strong lighting conditions.
  • Hyper Sonic Motor (HSM), along with an internal focusing design, realizes quick and quiet autofocus performance as well as full-time manual focus override.
  • Minimum focusing distance of 11" and a 1:5 maximum magnification ratio benefits working with close-up subjects.
  • Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
