Sigma 17-40mm f/1.8 DC Art Lens
Sigma 17-40mm f/1.8 DC Art Lens
A Bright, Wide-to-Normal APS-C Zoom
Sigma introduces a new zoom lens for APS-C mirrorless cameras with an f/1.8 aperture throughout the entire zoom range, the 17-40mm f/1.8 DC Art Lens. Featuring prime-like optical performance and video-friendly design and functionality, its wide-to-normal focal range means a lighter kit bag without surrendering image quality.
Design and Performance
The lens features a total of 17 elements in 11 groups, with four aspherical and four Special Low Dispersion elements to minimise flare and ghosting and suppress various aberrations. This results in an optical performance that meets or exceeds that of other Sigma Art lenses, including the 18-35mm f/1.8 DC HSM Art lens. Along with its 11-blade, rounded diaphragm, the design promotes sharpness and a large, smooth bokeh when used wide open.
In addition to the f/1.8 maximum aperture, the lens also maintains an 11" minimum focusing distance across the entire zoom range. It achieves a maximum magnification ratio of 1:4.8 at its longest focal length, increasing depth of field and versatility in tight spaces.
Video Production
Designed with video creation in mind, the lens' bright f/1.8 aperture and wide-to-normal zoom range make it a versatile tool ideal for single-shooter, run-and-gun setups. An internal zoom design maintains the overall length during use, making it easy to balance on gimbals. The design also suppresses focus breathing for smooth movement across the focal range. Sigma's high-speed, high-response linear actuator autofocus remains both quiet and accurate, while manual focusing is improved with click-and-lock mechanisms.
The lens also supports switching between linear and non-linear focus ring settings. With a rotation angle of 120 to 720° and a constant minimum focusing distance, operators will benefit from intuitive manual focusing at any focal length.
