Sigma introduce 17-35mm f/2.8-4 EX DG Aspherical HSM - New super wide-angle zoom lens with a 104 degrees angle of view and large f/2.8 aperture
The lens has a minimum focusing distance of 27cm at all focal lengths and maximum magnification ratio of 1:4.5.
Its HSM (Hyper Sonic Motor) for Sigma, Nikon and Canon mounts provides quiet, high-speed autofocus shooting, as well as full-time manual focus. It is easy to revert to Manual Focus by simply turning the focusing ring and overriding the AF.
Inner Focus System
The SLD (Special Low Dispersion) glass element and moulded glass aspherical lenses offer excellent correction for distortion as well as all types of aberration.
The sturdy EX build quality features an inner focus system that provides high performance and convenience and its non-rotating lens barrel suits the matched petal shaped lens hood and allows use of a circular polarizing filter.
