18-35mm f/1.8 DC HSM ART - Canon EF-S Fit

The Sigma 18-35mm f/1.8 DC HSM Art Lens for Canon EF is a wide-angle to normal zoom designed for APS-C-format cameras, offering a 28.8-56mm equivalent focal length range. This lens is distinguished by its constant f/1.8 maximum aperture, which enables shooting in low-light conditions and provides significant depth-of-field control for creative work. The optical design incorporates five Special Low Dispersion elements and four aspherical elements to minimize chromatic aberration and distortion while maintaining sharp, accurate image rendering.

The lens features a Hyper Sonic Motor for fast and quiet autofocus with internal focusing, combined with a Super Multi-Layer Coating to reduce lens flare and ghosting. Construction includes a Thermally Stable Composite material and brass bayonet mount for precision and durability. A rounded nine-blade diaphragm contributes to smooth bokeh quality, and the lens is compatible with Sigma's USB Dock for firmware updates and optical adjustments.
