The Sigma 14-24mm f2.8 ART is an ultra-wide angle zoom lens that’s designed for full-frame cameras and available in Canon, Nikon and Sigma mounts. Announced in February 2018, it’s the latest zoom in Sigma’s high-end ART series.
The lens delivers ultra-wide coverage and a constant f2.8 focal ratio. The optical design features three FLD elements, three SLD elements, and three aspherical elements, including one large-diameter aspherical element. The latter is responsible for Sigma’s claims of minimal distortion at 1% or less.
The lens employs 17 elements in 11 groups with nine rounded aperture blades and a minimum focusing distance of 26-28cm for a maximum magnification of 1:5.4. The dust and spash-proof barrel measures 96mm in diameter, 135mm in length and weighs 1150g. Like most ultra-wide lenses, the Sigma 14-24mm f2.8 ART has a built-in petal hood, but uniquely it can be converted by Sigma to a shorter rounded design to prevent or minimize issues with shadows or other lenses in multi-camera VR environments. The Canon version of the lens is also compatible with the lens aberration corrections available in recent bodies to compensate for vignetting, chromatic aberrations and distortion.
The Sigma 14-24mm f2.8 ART goes directly up against other ultra-wide zooms, most notably Nikon’s AF-S 14-24mm f2.8 and Canon’s EF 11-24mm f4 models. We look forward to comparing it against key rivals soon!
