Sigma 17-40mm F1.8 DC Art Sony E-mount

The Evolution of the F1.8 Zoom

The Sigma 17-40mm F1.8 DC Art represents a significant leap forward in optical engineering. Building on the legacy of the world-renowned 18-35mm F1.8, this next-generation lens offers a wider focal range while achieving a weight reduction of over 30%. It is designed specifically for Sony E-mount APS-C mirrorless cameras, providing a versatile standard zoom that rivals the performance of multiple prime lenses.

Professional Optical Performance

As part of the prestigious Art line, this lens is crafted for ultimate image quality. The constant F1.8 aperture allows for stunning bokeh and superior performance in low-light environments. Whether capturing wide landscapes at 17mm or intimate portraits at 40mm, the lens maintains edge-to-edge sharpness and clarity throughout the zoom range.

Advanced Autofocus and Video Features

Equipped with Sigma's HLA (High-response Linear Actuator), the autofocus system is both incredibly fast and nearly silent. For filmmakers, the lens features an inner zoom mechanism, meaning the physical length does not change during operation. Combined with suppressed focus breathing, it provides the stability and precision required for high-end video production.
