Overview
The Sigma 17-40mm f/1.8 DC Art Lens is a new zoom lens for APS-C mirrorless cameras, offering an f/1.8 aperture throughout the entire zoom range. It combines prime-like optical performance with a video-friendly design, providing a wide-to-normal focal range that ensures a lighter kit bag without compromising image quality.
Core Features
A Bright, Wide-to-Normal APS-C Zoom
The lens features a total of 17 elements in 11 groups, including four aspherical and four Special Low Dispersion elements to minimize flare and ghosting. This design suppresses various aberrations, resulting in optical performance that meets or exceeds other Sigma Art lenses. The 11-blade, rounded diaphragm promotes sharpness and a large, smooth bokeh when used wide open.
With an f/1.8 maximum aperture, the lens maintains an 11 cm minimum focusing distance across the entire zoom range. It achieves a maximum magnification ratio of 1:4.8 at its longest focal length, enhancing depth of field and versatility in tight spaces.
Design and Performance
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, facilitating 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 is both quiet and accurate, while manual focusing is enhanced with click-and-lock mechanisms.
Additional Features
- Two AFL buttons
- Focus mode switch
- Water- and oil-repellent coating on front element
- Dust- and splash-resistant design
- Durable brass bayonet mount
