Sigma has announced that its 70mm f/2.8 DG MACRO Art price tag will be £499.99. The Canon mount version will be available at the end of May, while the Sigma and Sony FE mount version release dates are still to be announced.
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 the 70mm f/2.8 lens’s 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.
