Sigma announces 105mm f/1.4 Art, 70mm f/2.8 Macro Art, expands range to Sony E mount


Sigma has announced the development of new new 105mm f/1.4 Art and 70mm f/2.8 Macro Art lenses and will be expanding its Art range to Sony E mount cameras.

The ninth lens in Sigma’s f/1.4 range, the 105mm F1.4 DG HSM Art comprises 17 elements in 12 groups and produces strong bokeh and minimal aberrations, Sigma says.

THe Sigma 105mm f/1.4 Art also boasts a dust- and splash-proof design. It will be available in Canon, Nikon and Sony E mounts.

The Sigma 70mm f/2.8 DG MACRO Art is the first macro lens in the company’s Art series and offers true 1:1 reproduction.

Sigma says its optical construction helps it achieve precise focus via an extending, floating, two-group focus mechanism. This configuration helps minimise aberrations, and to minimize axial chromatic aberration, the optical system incorporates two FLD glass elements, two SLD glass elements, and one element with a high rate of anomalous partial dispersion and a high index of refraction, Sigma says.

Two aspherical lens elements also help the 70mm f/2.8 macro increase resolution at close shooting distances.

Sigma says the 70mm f/2.8 macro also employs a focus-by-wire system that eliminates the direct mechanical connection between the focus ring and the focus drive system for more precise focus, while a new coreless DC motor reduces noise.

The Sigma 70mm f/2.8 Art macro lens is compatible with Canon, Nikon and Sony E mounts.

Sigma said it will begin introducing its Art lenses, which include

  • 14mm F1.8 DG HSM Art
  • 20mm F1.4 DG HSM Art
  • 24mm F1.4 DG HSM Art
  • 35mm F1.4 DG HSM Art
  • 50mm F1.4 DG HSM Art
  • 70mm F2.8 DG MACRO Art
  • 85mm F1.4 DG HSM Art
  • 105mm F1.4 DG HSM Art
  • 135mm F1.8 DG HSM Art

to Sony’s full-frame E mount. Sigma says the new E-mount models will feature a newly developed control algorithm to optimise AF drive and data transmission speed in the Sony cameras.

What’s more, the new Sigma lenses will be compatible with Sony’s continuous autofocus (AF-C) and high-speed autofocus, which are not addressed by the Sigma MC-11 Mount Converter.

The Sony E-mount lenses will also be compatible with in-camera image stabilisation and aberration correction.
