Sigma 17-40mm f/1.8 DC Art Lens for Sony E-Mount

Standard zoom lens with a large aperture and descriptive power comparable to a prime lens

Constant maximum aperture of F1.8

The 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 performance

The 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 fl are, the lens achieves high resolution even at the wide-open F1.8 aperture, rendering delicate textures and fi ne details with stunning clarity.

Flexible framing made possible

The 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 (1). 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.

1. Approximately 27.2-64mm for the Canon RF Mount version.

Designed to minimize fl are and ghosting

Using advanced simulation technology and Sigma’s Super Multi-Layer Coating, fl are and ghosting have been largely eliminated, ensuring that the lens renders rich, high-contrast results in all conditions.

Highly portable and versatile for any situation

Practical and stable inner zoom

Employing 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 design

The Sigma 17-40mm F1.8 DC | Art is over 30% lighter and has a fi lter 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 (1) / water- and oil-repellent coating

In 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.

1. The product is designed to be dust- and splash-resistant but is not waterproof. When using the lens near water, etc., 　take care not to allow large amounts of water to splash on it. If water gets inside the lens, it may cause a major malfunction 　 　and render the lens unrepairable.

Equipped with two AFL buttons

Equipped with two AFL buttons (1) (2) 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.

1. Functions can be assigned on supported cameras only. Available functions may vary depending on the camera used.

2. The FUJIFILM X Mount version has an AF function button that can be used to select AF lock/AF operation via lens switch.

Functions that support video production

HLA-driven high-speed AF

The 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.

Minimal focus breathing

The focus breathing is suppressed, minimizing changes in the angle of view caused by focus shift and enabling smooth, natural-looking focus pulls when recording video.

Aperture ring with various functions

Equipped with an aperture ring (1) for intuitive control of the aperture. When shooting video, users can turn off the click switch for smooth, quiet aperture control. It also has an aperture ring lock switch (2) to prevent accidental changes to the aperture during shooting.

1. The Canon RF Mount version has a control ring instead of an aperture ring. It does not have an aperture ring click switch or 　 　 lock switch.

2. If you turn it on in position A, the aperture ring will be locked in position A. If you turn it on in a position other than A, it will be 　 locked in the range from open to minimum aperture, and it will not be possible to turn it to position A.
