The Sigma 17-40mm f1.8 DC Art lens boasts excellent optical performance, a result of cutting-edge design and processing technologies, including the incorporation of high-precision aspherical lenses. Its optical design specifically prioritises the correction of axial chromatic aberration and sagittal coma flare, delivering high resolution and rendering delicate textures and fine details with stunning clarity, even at its wide-open F1.8 aperture. Furthermore, advanced simulation technology and Sigma’s proprietary Super Multi-Layer Coating have been employed to largely eliminate flare and ghosting, ensuring consistently rich, high-contrast results in all shooting conditions.

This lens features two customisable AFL buttons, strategically placed on both the side and top. This thoughtful positioning ensures users can easily access and operate these buttons, regardless of whether they’re shooting in landscape or portrait orientation. Each button can be assigned any desired function directly from the camera’s menu, offering enhanced versatility.
