The Sigma 17-40mm F1.8 DC Art is a highly advanced wide-angle lens specifically designed for mirrorless cameras with APS-C sensors. With a large aperture of F1.8, it delivers exceptional image quality comparable to that of a prime lens. This lens is not only compact and versatile but also ideal for various photographic and videographic applications. It allows for creative expression and pushes the boundaries of image design through its innovative optics and construction. The Sigma 17-40mm F1.8 DC Art is the result of years of research and development, offering an improved focal length and a weight reduction of over 30% compared to its predecessor, the Sigma 18-35mm F1.8 DC HSM Art. The fast and quiet autofocus, powered by the High-Response Linear Actuator (HLA), ensures precise focusing in any situation.

The Sigma zoom leaves an excellent impression, especially mechanically. Thanks to the internal zoom, quiet autofocus and reduced focus breathing, it is also a recommendation for film makers. The optical performance is very good with slight limitations at open aperture, primarily at 17 and 40 mm.
While lenses with an aperture of f/2.8 are also available in the APS-C range in various focal length ranges, you have to search longer for faster variants. Sigma is now filling this gap with its new 17-40 mm F1.8. But why should you go for such a fast lens in the first place? There are indeed differences in bokeh and sharpness in direct comparison - at a very high level, mind you.
