Sigma 17-40mm f/1.8 DC (A) F/ RF-Mount lens

The Sigma 17-40mm f/1.8 DC Art lens is a groundbreaking standard zoom lens, specifically designed for mirrorless APS-C cameras with a Canon RF mount. This lens builds on the success of its predecessor, the Sigma 18-35mm f/1.8 DC HSM Art, by offering a wider zoom range of 17-40mm. Despite the improved specifications, the weight has been reduced by more than 30%, significantly increasing mobility. The lens maintains a constant maximum aperture of f/1.8 across the entire zoom range, comparable to the performance of prime lenses. This makes it extremely suitable for shooting in low-light situations, such as indoor or night shots, and for creating images with beautiful bokeh. The optical construction, consisting of 17 elements in 11 groups, guarantees excellent image quality with minimal aberrations and high resolution, even at wide apertures. The lens features fast and quiet HLA autofocus, an internal zoom mechanism, and minimal focus breathing, making it ideal for both photography and videography. Additionally, the water- and oil-repellent coating on the front lens, along with the dust- and splash-proof construction, provides protection under various conditions. The compact and lightweight design, combined with functionalities such as programmable AFL buttons and a functional aperture ring (or control ring for RF-mount), makes this lens a versatile choice for creative image-makers.
