Sigma 17-40mm F1.8 DC | Art
The Sigma 17-40mm F1.8 DC | Art redefines what a standard zoom can do for APS-C creators. With a constant f/1.8 aperture throughout its range, it delivers consistent brightness, smooth bokeh, and professional-level depth control — qualities rarely found in zoom lenses.
This lens houses 17 elements in 11 groups, including multiple aspherical and SLD elements that reduce chromatic aberration and distortion. The result is edge-to-edge sharpness and vibrant contrast, even in challenging lighting conditions.
The internal zoom mechanism ensures that the lens length remains fixed while zooming — a major advantage for gimbal users and video creators. The High-response Linear Actuator (HLA) autofocus motor provides rapid, quiet focusing performance suitable for both stills and video.
Its 11-blade rounded diaphragm enhances the smoothness of background blur, while the minimum focusing distance of 28 cm allows for close-up creative compositions. The body is built to professional standards, featuring a dust- and splash-resistant design with a water- and oil-repellent coating on the front element.
Despite its fast aperture and professional optics, the lens remains compact at only 535 g, making it a reliable companion for travel, events, and hybrid productions.
Whether you’re a photographer or filmmaker, the Sigma 17-40mm F1.8 DC | Art offers unmatched performance, flexibility, and reliability — a lens that truly bridges the gap between prime sharpness and zoom convenience.
