The SIGMA 17-40mm f/1.8 DC Art is a zoom lens for APS-C mirrorless cameras, perfect for both photographers and videographers. Experience the image quality of a prime lens with this fast zoom lens featuring a maximum aperture of f/1.8 across the entire range.

The SIGMA 17-40mm f/1.8 DC Art builds on the 18-35mm f/1.8 DC HSM Art, released thirteen years earlier. The 17-40mm offers even better optical performance, a wider range, and a weight saving of more than 30%. The lens is more compact than its predecessor, making it perfect for travel, everyday photography, and video work where mobility is key.
The SIGMA 17-40mm f/1.8 DC Art features an exceptionally fast and quiet autofocus thanks to the HLA (High-response Linear Actuator), ideal in situations where absolute silence is essential. The lens has an internal zoom design that is equally convenient when used on a gimbal, tripod, or handheld — the overall length of the lens remains constant during zooming or focusing. The 17-40mm has a highly advanced optical construction and is equipped with Super Multi-Layer Coating. It consists of 17 elements in 11 groups, including 4 SLD and 4 aspherical lens elements. This results in an extremely precise, sharp, and clear lens that accurately corrects chromatic aberrations and lens flare. It is dust- and splash-resistant and features a water- and oil-repellent coating on the front element, keeping you prepared for changing weather conditions.
The SIGMA 17-40mm f/1.8 DC Art is fully customisable to suit your workflow. On the side and top of the lens you'll find an AFL button, to which you can assign specific functions via your camera for optimal control from any angle. The lens also features a control ring and a lock switch to prevent unintended adjustments.
The zoom range of the SIGMA 17-40mm f/1.8 DC Art (27.2–64mm in full frame) makes this lens an excellent choice for a wide variety of applications, from wide angle to portrait. Ideal for photographers and videographers looking for a fast zoom lens who don't want to keep switching lenses.
