When we first received news of this release, it seemed a bit odd–and then it made sense. Today, Sigma is announcing the new 24-35mm f2 DG HSM Art lens for full frame DSLRs. Yes, that’s right–the one was designed for full frame cameras and at the time of writing this post, the Sigma 24-35mm f2 is the fastest constant aperture full frame zoom lens designed for photography. According to the press release, this lens has updated AF algorithms that should make it one of the fastest lenses to autofocus. Of course, the fact that it’s also a wide angle lens sure does help.

The 24-35mm f2 is said to boast large-diameter aspherical lens elements, one “F” Low Dispersion (FLD) glass, and seven Special Low Dispersion (SLD) glass elements with two aspherical lenses.

Additionally, it has manual focus override, silent focusing, an inner focusing system, nine aperture blades, 18 elements in 13 groups, and weights 33.2 oz.

When the Sigma 24-35mm f2 launches, it will be available for Canon EF, Nikon F and Sony A mounts. No word on pricing yet though, but keep your eyes peeled.
