The Sigma 17-40mm f/1.8 DC Art Lens (Sony E) is designed to be used with mirrorless cameras featuring the APS-C Sony E lens mount. A fast aperture of f/1.8 is maintained throughout the entire zoom range.

The Sigma 17-40mm f/1.8 DC Art Lens offers prime-like optical performance along with a video-friendly design and functionality. It features a total of 17 elements in 11 groups, along with four aspherical and four Special Low Dispersion elements to minimise flare and ghosting and suppress various aberrations.

With a wide-to-normal zoom range, this versatile zoom range makes it an ultra-versatile tool for a single shooter and run-and-gun setups. Sigma’s high-speed, high-response linear actuator autofocus remains both quiet and accurate.
