Sigma 18-35mm f/1.8 DC HSM Art Zoom Camera Lens

Designed specifically for APS-C sized sensors, the 18-35mm f/1.8 DC HSM from Sigma is a innovative wide-angle to standard zoom lens that's achieved a continuous, super-bright f/1.8 aperture. Now you can shoot from landscapes to portraits - product shots to architecture - still lifes to close-up photographs - as the internal focusing and zooming allows for more usability and functionality.

Sigma’s already-legendary Art lenses are notable for their cutting-edge optical designs and rugged performance, making them ideal for the most creative and artistic applications. Relatively small in size for a fast f/1.8 lens, it measures 3.1” x 4.8” and weighs 28.6 oz. This Art lens has a constant aperture ranging from f/1.8 to f/16 and utilizes 9 diaphragm blades, the front accepts 72mm filters, along with a petal-shaped hood and caps that are included.

Additional highlights include compatibility with Sigma’s USB Dock, allowing users to update the lens firmware and adjust various parameter, such as focus; while the Hyper Sonic Motor (HSM) ensures smooth, fast and accurate autofocusing. The use of Thermally Composite Material (TSC) reduces size and weight but increases accuracy of the lens construction. Its optics are made possible by a wide molded aspherical lens with special Low Dispersion (SLD) glass. SLD glass corrects for chromatic aberration and curvature at the widest angles.
