Sigma Art 18-35mm F1.8 DC HSM is a large-aperture fixed focal length lens is great for achieving expressive bokeh effects and enjoying ultra-high optical performance. On the other hand, photographers often need to change the angle of view to properly capture the scene that presents itself. To solve this decades-long dilemma, SIGMA proudly introduces the 18-35mm F1.8 DC HSM next-generation large-aperture APS-C format standard zoom lens for digital SLR cameras. Taking on the challenge of creating the world’s first* wide-aperture lens to offer an aperture of F1.8 throughout the zoom range, SIGMA has succeeded in creating a zoom lens that offers the same high optical performance of a fixed focal length lens. These outstanding performance characteristics are especially apparent in an APS-C format camera, since it has a slightly greater depth of focus than a full-frame camera. This is a revolutionary lens that overturns preconceptions while expanding the range of photographic expression. Covering the angles of view offered by multiple large-aperture, fixed focal length lenses, this lens combines advanced flexibility with uncompromising performance. Zoom lenses are extremely convenient, providing a wide range of angles of view with just a twist of the zoom ring. The downside, however, is that F2.8 has been the limit of zoom lens brightness, forcing photographers to select fixed focal length lenses for brighter f-numbers. Although fixed focal lenses have been superior to zoom lenses in terms of f-number brightness and overall performance, they offer only a fixed angle of view, requiring photographers to carry several with them and change lenses as necessary. The 18-35mm F1.8 DC HSM next-generation large-aperture standard zoom lens is the world’s first* to deliver F1.8 brightness throughout the zoom range. Its bright viewfinder makes it easy to confirm focus and compose perfect shots. As compared to a F2.8 lens in the same photographic conditions, it allows the photographer to use a shutter speed that is one stop faster, reducing the influence of camera shake. In addition, the shallower depth of field makes possible a beautiful bokeh effect in the background, expanding photographic creativity. From wide open to standard apertures, this lens is highly flexible, covering the angles of view offered by multiple large-aperture, fixed focal length lenses.Sigma Art 18-35mm - EF Mount The definitive large-aperture APS-C format standard zoom lens.
