The lens is designed for APS-C sensor cameras
Designed for APS-C cameras with a fast f/1.8 aperture, the Sigma 18-35mm wide-angle zoom lens is a unique combination of the flexibility of a zoom lens and the image quality of a prime lens. The wide-angle to normal focal length, high aperture, circular diaphragm, and short focusing distance allow, in skilled hands, images that would normally require two to three expensive prime lenses to capture.
