Sigma 17-40mm F1.8 DC ART RF MOUNTproduct description
Revolutionary F1.8 Standard Zoom for Canon RF Mount
The Sigma 17-40mm F1.8 DC Art represents a significant leap in optical engineering, succeeding the legendary 18-35mm F1.8. Designed specifically for APS-C mirrorless cameras, this lens provides a versatile wide-to-standard focal range with a constant large aperture, delivering prime-lens quality across the entire zoom spectrum.
Advanced Optical Performance and Portability
Despite its wider 17-40mm range, Sigma has achieved a weight reduction of over 30% compared to its predecessor. This makes it an ideal companion for handheld shooting and gimbal work. The lens maintains exceptional sharpness and contrast, meeting the high standards of the Sigma Art line.
Optimized for Professional Video Production
Equipped with a High-response Linear Actuator (HLA), the autofocus is both lightning-fast and near-silent. Filmmakers will appreciate the inner zoom mechanism, which keeps the lens barrel length constant, and the suppressed focus breathing that ensures stable framing during focus pulls.
