Sigma 17–40Mm F1.8 Dc Art Lens - Canon Rf In Black

The Sigma 1740mm F1.8 DC Art is a portable, durable and versatile standard AF zoom lens compatible with Canon APS-C mirrorless cameras. The constant maximum aperture of F1.8 makes it ideal for low-light settings 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 fl are, the lens achieves high resolution even at the wide-open F1.8 aperture, rendering delicate textures and fine details with stunning clarity. 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 ring1 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 switch2 to prevent accidental changes to the aperture during shooting. Designed to minimize flare and ghosting Using advanced simulation technology and Sigmas Super Multi-Layer Coating, fl are and ghosting have been largely eliminated, ensuring that the lens renders rich, high-contrast results in all conditions. 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. Durable design 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.
