The Sigma 24-35mm F2 DG HSM | Art is the world’s first full-frame zoom lens with a constant F2 maximum aperture, and its 1.45x zoom range manages to bridge three of the most popular wide angle fixed focal lengths for lenses: 24mm, 28mm and 35mm. The zoom range is subtle, but the compositional effects are noticeable as the smooth zoom ring shifts the field of view from 24mm through to 35mm. The lens is now shipping with a $999 street price.
It is an Art lens—it is designed first and foremost with an eye and intention on total image quality. The build, heft, and hand feel is completely in line with the others in the Art stable. At 33.2 ounces with a 3.4 inch diameter barrel that’s 4.8 inches long without lens hood, it is slightly larger than the 18-35 F1.8 DC HSM | Art lens, due to the larger, full-frame imaging circle.
And it weighs ten ounces more, and is an inch and a quarter longer than the 24mm F1.4 DG HSM | Art lens. The design intention of the Art line is focused on total imaging performance, and these lenses do have a presence when mounted to a camera. It has some weight, but it is well balanced and feels great matched with a full-frame DSLR.
It is a Sigma Global Vision lens. That means every single unit is individually tested on our exclusive A1 MTF device for sharpness. And it is customizable with the USB Dock. And it can have its mount switched between any released mounts through our exclusive Mount Conversion Service.
Through the lens, it feels more like a big fast prime, than a zoom. The F2 maximum aperture shows shallow depth of field, especially when close-focused, and is very sharp and contrasty on the focal plane. And then with a twist of the zoom ring, the scene shifts and the feel of the background blur tells you you’re not at 24mm any more, but instead glided smoothly to 28mm, 30mm, and then to 35mm.
True, this lens is a stop slower than the 24mm F1.4 DG HSM | Art and 35mm F1.4 DG HSM | Art prime lenses it matches at the wide and long end of the focal range, and is a third of a stop faster than the classic Sigma 28mm F1.8 prime at the middle; but for photographers who crave the convenience of a zoom lens, that is a very fair trade-off to make. And looking at the first batch of images I’ve made, the 24-35mm F2 DG HSM | Art lens delivers the legendary wide-open sharpness that is one of the defining characteristics of this line.
