SIGMA Corporation introduces the SIGMA 18-50mm F2.8 DC DN Contemporary Lens for Canon RF Mount - a large F2.8 aperture zoom lens that need never leave your camera. This exceptionally light, bright, and sharp standard zoom for crop-sensor mirrorless cameras is the ultimate workhorse lens.
Long-Awaited Canon RF Mount Addition
SIGMA's first APS-C size mirrorless dedicated zoom lens, the SIGMA 18-50mm F2.8 DC DN Contemporary, will now be available for the Canon RF Mount. This addition allows users to enjoy high-performance, and high-quality SIGMA zoom lenses in native mount on their Canon RF Mount system. A control algorithm including AF drive and communication speed optimization has been developed specifically for Canon RF Mount mirrorless lenses. In addition to realizing high-speed AF, the lens also supports Servo AF and in-camera aberration correction. The mount is rubber-sealed to cater for use in a variety of environments. Mount Conversion Service is available to convert other mounts of SIGMA 18-50mm F2.8 DC DN Contemporary to Canon RF Mount.
Large F2.8 Aperture and Superb Image Quality
The compact body offers a versatile full-frame equivalent zoom range of 28.8mm to 80mm, a wide aperture of F2.8 throughout the entire zoom range that allows you to enjoy bokeh expressions, and sharp images achieved by the latest optical design technology. With a minimum focusing distance of 12.1cm and a maximum magnification of 1:2.8, it allows photographers to take advantage of the compact shooting system, such as shooting close-ups of your subject.
Exceptionally Compact and Lightweight Body Ideal for Mirrorless Cameras
The main feature of the SIGMA 18-50mm F2.8 DC DN Contemporary is its overwhelmingly compact and lightweight body that maximizes the excellent portability and advantages of an APS-C mirrorless camera. Despite its large aperture of F2.8, it is the smallest and lightest in its class boasting a maximum diameter of 69.2mm, a length of 74.5mm, and weight of 300g. This makes the large-aperture standard zoom easy to carry around in daily life.
