The Sigma A 18-35mm f/1.8 DC HSM is an ultra fast standard zoom lens for DSLR APS-C/DX format cameras only.

The optical scheme of the lens comprises 17 elements in 12 groups, including four glassmold aspherical elements and five SLD elements. A Super multi-layer coating is applied to minimize flare and ghosting and produce high contrast images even in back light.

An internal focusing and zooming system helps to maintain a consistent overall length. The front element does not rotate facilitating the use of polarizing filters.

A hyper sonic AF motor with FTM and optimized AF algorithm provides silent and fast focusing The lens is equipped with a 9-blade circular diaphragm. LH780-03 petal lens hood included. The lens has a year of manufacture on the barrel.
