Guessing that this may be on the pricy side for a Sigma, but still undercut native options and be sharp as hell to boot.
Sigma has announced a new 14-24mm F2.8 HSM Art lens for full-frame Canon, Nikon and Sigma DSLRs. This ultra-wide zoom has three FLD and three SLD glass elements, plus an 80mm 'high precision molded' aspherical element. The lens is sealed against dust and moisture and has a nine-blade aperture, minimum focus distance of 26cm (10") and a weight of around 1.2 kg (2.5 lb).
While the 14-24 comes with a petal-shaped hood, Sigma will offer a 'front mount conversion service' that will replace it with a circular hood, which is preferable when capturing content intended for VR use.
Living up to its Art designation, the 14-24mm has been designed with 50MP sensors in mind. It claims to minimize distortion to 1% or lower when focused to infinity, and the Canon mount version of the lens works with Canon's in-camera lens aberration correction. Each 14-24mm F2.8 comes from Sigma's Aizu, Japan factory.
Pricing and availability information will be released at a later date.
