Spanning wide-angle to telephoto, the Sony A-mount 18-250mm f/3.5-6.3 DC Macro HSM from Sigma is an all-in-one zoom offering great versatility within a sleek form factor. The 27-375mm equivalent range is complemented by an advanced optical design that uses low dispersion and aspherical elements to reduce aberrations and distortion throughout the zoom range. A Super Multi-Layer Coating has also been applied to control flare and ghosting for improved contrast and color fidelity. Additionally, balancing the optics, the zoom also features a Hyper Sonic Motor, which provides quick, smooth, and quiet autofocus performance with full-time manual focus override.

  • All-in-one zoom is designed for APS-C-format Sony A-mount cameras and provides a 27-375mm equivalent focal length range.
  • One Special Low Dispersion (SLD) element is featured in the optical design and helps 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 1.1' and a 1:2.9 maximum magnification ratio benefits working with close-up subjects.
  • Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity.
  • Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
