Truly a revolutionary product, the Sigma 18-35mm 1.8 DC HSM is the first wide-angle to standard zoom lens to achieve a large aperture of 1.8. Designed specifically for APS-C sized sensors, the Sigma 18-35mm 1.8 translates to 27mm-52.5mm on 35mm camera. Tapping into Sigma’s long history of lens innovations, the 18-35mm 1.8 DC HSM incorporates a wide glass molded aspherical lens with Special Low Dispersion (SLD) glass to compensate for aberrations and curvature at the widest angle. Internal focusing and zooming allows for more usability and functionality. The 18-35mm is ideal for landscape photography, portrait photography, still life photography, snap shots, casual photography, and close-ups and 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. Its new Global Vision design works features compatibility with the Sigma USB dock for further customization. A 9 blade rounded diaphragm also creates beautiful background blur. The Sigma 18-35mm 1.8 DC HSM is a new benchmark in photographic history and a must have for every camera bag.

USB Dock Compatibility Sigma has developed special software (SIGMA Optimization Pro) that can update the lens firmware and adjust parameters such as focus.

*USB Dock is sold separately.

“The lens is impressively sharp at f/1.8.” -PC Mag

“The Sigma 18-35mm F1.8 DC HSM captures twice as much light as an f/2.8 zoom and delivers more consistent sharpness than Canon's 17-55mm.” -PC Mag

“The 18-35mm isn't just sharp for a fast zoom; in terms of outright image quality, it's a match for many fast primes, even when shot wide open.” - Dpreview

“Super-fast and super accurate are just some of the words that we’re going to use to define the focusing on the new Sigma 18-35mm f1.8.” -The Phoblographer

“We’ve got absolutely nothing but respect and love for the Sigma 18-35mm f1.8 DC HSM.”- The Phoblographer

“Best performing APS-c zoom in our database.” -DxOMark

“Ultra-fast lenses don’t usually perform well at full-aperture, let alone high-speed zooms that before this lens arrived usually meant a maximum aperture of f/2.8, but this one bucks that trend.” - DxOMark

“From what we've seen so far, this is going to be an absolutely killer lens.” -Imaging Resource

“Not only were images very sharp, even at f/1.8, but chromatic aberration, vignetting and distortion were all very well-controlled.” -Imaging Resource
