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.

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.
