“The Best lowlight zoom lens for a mile.” -Gizmodo

“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
