Sigma has released a Sony AF version of its 105mm f/2.8 EX DG OS HSM lens.

Marketed as a large aperture, medium telephoto, macro lens the newcomer incorporates Sigma’s Optical Stabilisation (OS) system.

Features include a splash-resistant design, plus a Special Low Dispersion (SLD) lens and a high refractive index SLD lens, claimed to deliver ‘excellent correction for all types of aberration and distortion’.

The nine diaphragm-blade optic is built from 16 elements in 11 groups and boasts a maximum magnification ratio of 1:1.

The 725g lens, which replaces the Sigma Macro 105mm f/2.8 EX DG launched eight years ago, costs £649.99.
