It’s really hard to argue Sigma isn’t on a roll these days. The Art line of their new global vision initiative have been cleaning up, with serious and well-liked entries like their 50mm f1.4, 35mm f1.4, and that amazing 18-35mm f1.8 that’s essentially a direct 24-70mm f2.8 equivalent for crop cameras. And today they’ve announced yet another sure-to-be-a-winner upcoming lens, the world’s first (they claim) f2 constant full-frame zoom lens. Covering a range of 24-35mm, it’s intended to replace common prime entries in the 24mm, 28mm, and 35mm focal lengths, for those who need fast lenses but would prefer the convenience of a zoom to the super-wide f1.4 aperture in at least Sigma’s own offerings through that range. As with the other lenses in this line, it’s no simple lens with 18 elements in 13 groups, some of which are FLD and SLD glass.
The Sigma 24-35mm features a rounded 9 blade aperture will keep bokeh smooth, and it’s using their latest generation of HSM focusing motors. Like all lenses in the global vision it’s compatible with their USB dock if you want to fine-tune the AF performance for your style and bodies.
No word on price or availability of the Sigma 24-35 yet, but, as I have been with all the others in the ART line, I’m excited to see those myself as this would be a great addition to my kit.
