Sigma 105mm f/1.4 DG HSM Art lens

Digital Camera World Verdict

There’s no denying this is a big, heavy and expensive lens, but the Sigma 105mm f/1.4 Art delivers sumptuous image quality with immense sharpness and clarity, along with beautifully soft and creamy blur. For portraiture, it’s spectacular.

Why you can trust Digital Camera World Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out how we test.

Competing in the ring of ultimate portrait primes, Sigma’s latest Art lens is up against pro-grade favourites, including the Canon EF 85mm f/1.4L IS USM, Nikon AF-S 105mm f/1.4E ED and Sony FE 85mm f/1.4 G Master. The Sigma overshadows them all, if only in physical size and weight: it’s heavier than most 70-200mm f/2.8 telephoto zooms.

The optical design is based on 17 elements, laid out in 12 groups. These include three top-performance FLD (Fluorite-grade Low Dispersion) elements, two SLD (Special Low Dispersion) elements, and one aspherical element. Multi-layer coatings are applied and a fluorine coating is added to the front element, to repel moisture and fingerprints. Unlike many of Sigma’s older Art lenses, this one has weather seals, including a rubber gasket on the mounting plate.
