Sigma AF 17-40mm f1.8 DC Art Lens
The Sigma AF 17-40mm f1.8 DC Art Lens is designed for photographers and videographers seeking the perfect blend of flexibility, speed, and image quality. Engineered for cropped sensor performance, this standard zoom lens offers the brightness and clarity of a prime lens with the adaptability of a zoom. Whether you're capturing low-light portraits, expansive landscapes, or cinematic video content, this lens delivers exceptional results in any setting.
Constant F1.8 aperture
With a constant F1.8 aperture across the entire zoom range and a focal length covering 25.5-60mm in 35mm format, the Sigma 17-40mm opens up a world of creative possibilities. Its fast aperture allows for beautiful background separation with pronounced bokeh, making it ideal for portraits and artistic expression. Additionally, the wide aperture performs impressively in challenging lighting conditions, from indoor events to nighttime cityscapes, ensuring clean, detailed images with minimal noise.
Minimal flare and ghosting
A super multi-layer coating effectively suppresses flare and ghosting, helping to maintain high contrast and colour fidelity even in challenging lighting situations. The result is clear, vibrant images with excellent edge-to-edge sharpness throughout the zoom range.
High-speed AF
The lens is driven by Sigma’s advanced High-response Linear Actuator (HLA), ensuring rapid, quiet, and accurate autofocus. This high-speed AF is particularly well-suited for single-operator video production, such as vlogging or gimbal work.
Ideal for video
Focus breathing is minimised, allowing for smooth and natural transitions during focus pulls, while a 28cm minimum focusing distance further enhances versatility for dynamic close-ups.
Plus, an aperture ring* with a click switch enables silent adjustments during video recording, while an aperture ring lock switch helps prevent unintended changes.
*The Canon RF Mount version has a control ring instead of an aperture ring.
Compact and versatile
At just 535g and with a compact 67mm filter diameter, the Sigma 17-40mm F1.8 DC Art is over 30% lighter than its predecessor, making it a highly portable option for travel and everyday use. For user ease, the lens includes two customisable AFL buttons placed for convenient access in both landscape and portrait orientations.
Its robust construction features a dust- and splash-resistant design, while the front element is coated to repel water and oil, ensuring reliable performance in harsh outdoor environments.
