Sigma announces two new Art lenses
SIGMA has revealed two brand new Art lenses and has also announced that a further seven of its existing lenses will be made available in the Sony FE mount.
First of the two new additions is the Sigma 105mm f/1.4 DG HSM lens, which Sigma describes as the ‘bokeh master’. This is the longest focal-length lens in the Art series to feature an f/1.4 maximum aperture, and it brings the total number of Sigma lenses with such a fast aperture to nine, including six for full-frame cameras and three for APS- C models.
The second lens is the Sigma 70mm f/2.8 DG Macro lens, which is the first macro lens in Sigma’s Art lens line- up.
Sigma also revealed that it will be manufacturing nine Art prime lenses for Sony FE mount, which is found on Sony’s full-frame cameras, such as the new Sony Alpha 7 III (see page 8). Focal lengths from 14mm to 135mm will be covered by the new Sony FE mount line- up, including the two brand new models. Sigma says it plans to add more lenses to this mount option in the future.
The new 105mm f/1.4 DG HSM lens incorporates 17 optical elements in 12 groups. These include three FLD glass elements, two SLD glass elements and one aspherical lens element. This optical system is designed to minimise chromatic aberration, while simultaneously delivering beautiful bokeh in out- of-focus areas. Aimed primarily at portrait photographers, the lens boasts exceptional peripheral brightness, along with minimal vignetting.
Meanwhile, the 70mm f/2.8 DG Macro lens features an extending, floating, two- group focus mechanism. This is designed to minimise aberrations, with an optical system incorporating two FLD glass elements, two SLD glass elements and one element with a high rate of anomalous partial dispersion and high index of refraction.
Both lenses have a dust- and splash-proof structure, with special sealings at the mount connection. Other shared features include compatibility with Canon Lens Aberration Correction, fast AF with full-time manual override and a brass bayonet mount.
Both lenses will be available in Sigma, Canon and Sony mounts, while the 105mm f/1.4 lens will also be available for Nikon.
