Sigma wide zoom equals three primes

Sigma has added a fast wide-angle zoom, the Sigma 24-35mm F2 DG HSM Art,  to its market-disrupting Art range of premium full-frame lenses.

Sigma-24-35mm-f2(‘Market-disrupting’ because to date the made-in-Japan Art series lenses have been widely reviewed and bench-tested as equal or superior to their Canon and Nikon equivalents, but at a fraction of the price – with the pricing differential particularly marked in Australia.)

Sigma says this is the world’s first full-frame zoom lens with an f2 widest aperture. It effectively delivers three fast primes – 24mm, 28mm, and 35mm – in one unit. Aperture range is f2 – f16. Closest focusing is to 11-inches.

Now to the optical science mumbo-jumbo: The Sigma 24-35mm uses one ‘F’ low dispersion and seven special low dispersion glass elements in addition to two aspherical lenses, which minimises the appearance of spherical aberration, axial chromatic aberration and field curvature. Did we mention sagittal coma flare correction? That’s sorted, too. A super multi-layer coating reduces flare and ghosting.

The body of the 24-35mm is made of a ‘thermally stable composite’ and the barrel has a focus ring for manual override of the Hyper Sonic Motor-driven AF.

A lens hood is included, fitted with a rubber connection for a secure fit.

The Sigma 24-35mm F2 DG HSM Art is compatible with Sigma’s USB Dock for firmware updates and AF microadjustment.

The lens will be locally available in August, according to local distributor, CR Kennedy. Pricing has not been announced.
