Sigma has done it again! After their amazing 18-35mm f/1.8 DC HSM, they announced the Sigma 24-35mm f/2, a zoom lens that covers most commonly used focal lengths and stays at f/2 all the time!
It has a closest focusing distance of 28cm, 18 elements in 13 groups and 9 diaphragm blades, to get that good looking bokeh. Thanks to its closest focusing, and a maximum magnification ratio of 1:4.4, this lens is also good for close-ups and more than “just” landscape or indoor photography.
When focusing (as expected, it uses Hyper Sonic Motor for fast and accurate AF), the front element does not rotate, making it perfect for polarizing filters. To minimize aberration and curvature at wide angles, the Sigma 24-35mm uses 7 SLD (Special Low Dispersion) and 1 FLD (Fluoride Low Dispersion) elements.
No information about the price or release date yet, but it will be available for Canon, Nikon and Sigma mounts (both Full Frame and Crop cameras). If the lens will deliver as promised, Sigma will have 2 excellent fixed aperture zooms on the market!
