The Sigma 24-35mm f2 DG HSM Art lens is the world's first large aperture full-frame wide-angle lens offering a bright f/2.0 aperture throughout the zoom range. It allows photographers to carry one lens to do the work of three fixed focal length lenses, a 24mm, 28mm and 35mm - with f2 brightness and top optical performance. Premium FLD glass, with performance equal to flourite, and seven SLD glass elements allow for outstanding image quality. An updated AF algorithm makes for smooth, accurate and fast autofocusing while multi-layer coating control flare and ghosting.

Covering the range of three fixed focal length wide-angle lenses
Delivering excellent functionality and convenience, one lens offers quality equivalent to that of three high-performance fixed focal length lenses at F2 brightness: 24mm, 28mm and 35mm. With a minimum focusing distance of 28cm and a maximum magnification ratio of 1:4.4, this lens is suitable for close-up shooting, portraits with an attractive bokeh and deep-focus landscape photography. Photographers have access to angles of view equivalent to those of three wide-angle lenses without having to switch lenses. While achieving the desired background effect can be difficult with a conventional wide-angle lens, the large diameter of this lens allows photographers to open the aperture wide and use the shallow focus to achieve stunning results.
The outstanding optical performance of the fixed focal length lenses in SIGMA’s Art line
The SIGMA 24-35mm F2 DG HSM builds on the concept of the SIGMA 18-35mm F1.8 DC HSM | Art, the world’s first zoom lens to offer F1.8 brightness throughout the zoom range. Thanks to its outstanding optical performance, this lens provides the same quality as the high-performance fixed focal length lenses in the Art line.
Incorporating SIGMA’s latest technologies
To realize a large-diameter zoom lens for full-frame cameras with F2 brightness, SIGMA designed each and every part with uncompromising care and quality. The lens incorporates large-diameter aspherical lens elements, which require advanced technologies to manufacture; one FLD (“F” Low Dispersion)* glass element; and seven SLD (Special Low Dispersion) glass elements, of which two are aspherical lenses. The advanced optics and optimized lens power distribution minimize spherical aberration, axial chromatic aberration and field curvature, resulting in outstanding optical performance. Even at widest aperture, this lens delivers breathtaking image quality.
Flare and ghosting reduction
From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
The inner focusing system eliminates front lens rotation, enhancing the lens's stability and allowing use of circular polarizing filters. This is particularly convenient for shooting video.
Exclusive low-dispersion glass
The degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite. Meticulous deployment of these types of exclusive low-dispersion glass and optimization of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.
