Sigma 17-40mm f1.8 ART DC zoom lens for APS-C mirrorless cameras pushes the boundaries of still and video expression.
The Sigma 17-40mm F1.8 DC lens builds upon the groundbreaking innovations of the Sigma 18-35mm F1.8 DC HSM, 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.
Enjoy buttery bokeh and bright exposures at F1.8 throughout the full zoom range, from 17mm to 40mm. Perfect for low-light photography, indoor shoots, and nighttime portraits.
Thanks to 4 SLD elements and 4 aspherical lenses, the optical design delivers razor-sharp results with minimal aberration and stunning clarity even wide open at F1.8.
Covers a 35mm equivalent of 25.5-60mm (or 27.2-64mm on Canon RF), letting you go from wide-angle landscapes to portrait-ready shots without ever changing lenses.
Advanced Super Multi-Layer Coating and simulation tech ensure your images are clean, contrast-rich, and free of flare even in tough lighting.
Dual AFL buttons, placed for easy access in landscape or portrait mode, let you assign camera functions like AF lock or tracking to the lens itself.
Sigma’s High-response Linear Actuator (HLA) gives you lightning-fast and near-silent focusing which is ideal for vlogging, interviews, and run-and-gun filmmaking.
This Sigma ART DC lens suppresses focus breathing so your video focus transitions stay smooth and cinematic.
Enjoy precise and tactile manual aperture control with the de-click switch for silent operation. Lock your aperture ring in place to avoid accidental bumps.
Note: The Canon RF version uses a control ring instead.
Switch between auto and manual focus with the dedicated Focus Mode switch, conveniently placed for fast decisions in the field.
Sigma’s Mount Conversion Service can adapt your lens to a different mount, keeping your gear future-proof.
At just 535g (30% lighter than the 18-35mm predecessor), and with a slimmer 67mm filter size, this F1.8 zoom lens is surprisingly easy to carry. Travel-friendly meets pro-level power.
Tackle the elements with confidence, this lens has a sealed body and water and oil-repellent coating on the front element.
For L-Mount users, adjust the focus ring behavior to suit your shooting style: linear for manual video pulls, or non-linear for intuitive stills work.
Fine-tune firmware and performance settings using the optional USB Dock, designed specifically for L-Mount lenses.
