17-40mm F1.8 DC ART
This zoom lens for APS-C mirrorless cameras pushes the boundaries of still and video expression
The 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 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 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 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. 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 ghosting
Using 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 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 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 structure1/ 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 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
1to prevent accidental changes to the aperture during shooting.
1. 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
