Bundle - Sigma - 17-40mm f/1.8 DC Art Lens for Sony E, with Filter Kit

With an F1.8 large aperture and exceptional image quality comparable to a prime lens across the entire zoom rangeThis zoom lens for APS-C mirrorless cameras pushes the boundaries of still and video expressionThe Sigma 17-40mm F1.8 DC | Art builds upon the groundbreaking innovations of the Sigma 18-35mm F1.8 DC HSM | Art, which earned high acclaim as the world's first F1.8 zoom lens in the photography and video industry. Thirteen years after its debut, this next-generation lens achieves not only superior optical performance but also a wider focal length of 17-40mm while reducing its weight by over 30%. This dramatically enhances the versatility of a large aperture standard zoom lens.In addition to the fast and quiet autofocus driven by the HLA (High-response Linear Actuator), the lens incorporates an inner zoom mechanism and minimal focus breathing, ensuring outstanding performance for both still photography and video production. Sigma, the pioneer that stunned the world with the first-ever F1.8 zoom lens, has once again revolutionized the history of large aperture zoom lenses with groundbreaking advancements.Standard zoom lens with a large aperture and descriptive power comparable to a prime lensConstant maximum aperture of F1.8The Sigma 17-40mm F1.8 DC | Art has the convenience of a zoom lens with a constant aperture of F1.8 throughout the zoom range. Taking advantage of a large aperture comparable to a prime lens, the lens is suitable for low-light environments such as indoor and night scenes, as well as for expression using large bokeh.Excellent optical performanceThe optical design, realized through the latest design and processing technologies, including the use of high-precision aspherical lenses, achieves excellent optical performance.By emphasizing the correction of axial chromatic aberration and sagittal coma flare, the lens achieves high resolution even at the wide-open F1.8 aperture, rendering delicate textures and fine details with stunning clarity.Flexible framing made possibleThe zoom range of the Sigma 17-40mm F1.8 DC | Art has been expanded from its predecessor the Sigma 18-35mm F1.8 DC HSM | Art, covering 25.5-60mm in 35mm format. From wide-angle tabletop photography to portraits that fully utilize the telephoto angle of view, users can take full advantage of the expressive power of the large F1.8 aperture while freely framing their shots without the need to change lenses.Designed to minimize flare and ghostingUsing advanced simulation technology and Sigma's Super Multi-Layer Coating, flare and ghosting have been largely eliminated, ensuring that the lens renders rich, high-contrast results in all conditions.Highly portable and versatile for any situationPractical and stable inner zoomEmploying an inner zoom mechanism, the overall length of the lens remains constant when the focal length or focus distance changes. This means the lens is easy to use and highly stable when shooting hand-held, on a tripod or gimbal, and even more resistant to dust and water contamination.Enhanced mobility with a compact and lightweight designThe Sigma 17-40mm F1.8 DC | Art is over 30% lighter and has a filter diameter of 67mm, which is one size smaller than its predecessor the Sigma 18-35mm F1.8 DC HSM | Art. Despite being a large aperture zoom lens, it is surprisingly portable. The expressive power of F1.8 can be used with a compact APS-C system, making it ideal for travel and everyday photography, as well as video production, where mobility is key.Dust- and splash-resistant structure / water- and oil-repellent coatingIn addition to a dust- and splash-resistant structure, the frontmost surface of the lens has a water- and oil-repellent coating applied, so that the lens can be used safely even in harsh outdoor environments.Equipped with two AFL buttonsEquipped with two AFL buttons that can be assigned any function from the camera menu. By placing them on the side and top, users can easily operate the buttons in either landscape or portrait positioning.Functions that support video productionHLA-driven high-speed AFThe adoption of HLA (High-response Linear Actuator) enables quiet, high-speed, high-precision autofocus. The smooth, stable autofocus is perfect not only for still photography, but also for single-operator shooting with a gimbal or vlogging.
