Sigma 18-35mm f/1.8 DC HSM Art

One of the most remarkable lenses ever made for APS-C DSLRs — Sigma's 18-35mm f/1.8 DC HSM Art is the world's first zoom lens with a constant f/1.8 maximum aperture. Designed exclusively for APS-C sensors, it delivers a 27–53mm full-frame equivalent range at a speed that simply doesn't exist in any other zoom. Optically outstanding, it produces sharpness and bokeh that rivals prime lenses throughout the zoom range. The ultimate creative upgrade for Canon APS-C DSLR shooters. EF-S compatible, EF mount fitting.

GearFrame's Take

The world's only constant f/1.8 zoom — an extraordinary APS-C lens that renders like a prime at every focal length.
