Sigma 18-50mm f2.8 DC DN Contemporary Fujifilm X - 1319640
SIGMA's first APS-C size mirrorless dedicated zoom lens, the 18-50mm F2.8 DC DN | Contemporary, will now be available for the Fujifilm X Mount. This addition allows users to enjoy high-performance and high-quality SIGMA zoom lenses in native mount on their X Mount system.
The first three lenses in SIGMA's X Mount lineup were the wide-angle prime 16mm F1.4 DC DN | Contemporary, the standard prime 30mm F1.4 DC DN | Contemporary, and the telephoto prime 56mm F1.4 DC DN | Contemporary. The lineup consists of focal lengths making a complete system for mirrorless camera users. Now, with the addition of the 18-50mm F2.8 DC DN | Contemporary, a compact, lightweight, and high-performance large-aperture standard zoom lens, SIGMA offers a new option for this compact photographic system.
A control algorithm including AF drive and communication speed optimization has been developed specifically for X Mount interchangeable lenses. In addition to realizing high-speed AF, the lens also supports AF-C (Continuous AF) and in-camera aberration correction*. The mount is rubber-sealed to cater for use in a variety of environments.
The compact body offers an easy-to-use zoom range of 27mm to 75mm in the 35mm format, 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*1, it allows photographers to take advantage of the compact shooting system, such as shooting close-ups of your subject.
The main feature of the 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*2 boasting a maximum diameter of φ61.6mm, a length of 76.8mm, and a weight of 285g.*3 This makes the large-aperture standard zoom easy to carry around in daily life.
