High speed of F2.8 and superior image quality

The SIGMA 18-50mm F2.8 DC DN Contemporary covers the focal length range between 27 and 75mm (equivalent to 35mm format) - and does so with a consistent aperture of F2.8, making it ideally suited for portrait and close-up photography where you want to crop the subject against a blurred background that won't distract from the subject in focus due to the attractive, soft bokeh

With three high-precision, bright-molded aspheres and a reduction in the number of optical elements overall, the lens achieves superior image quality at a low weight. In-camera optical noise correction further helps eliminate aberrations such as distortion and vignetting. This performance is made possible by advanced lens development technology at SIGMA's sole manufacturing facility in Aizu, Japan, where all SIGMA lenses are produced.

Exceptionally lightweight and compact - ideal for mirrorless cameras

The SIGMA 18-50mm F2.8 DC DN Contemporary is remarkably lightweight and compact, making it a fitting complement to mirrorless APS-C cameras. It is the perfect standard zoom, ideal for everyday use and up to a wide range of shooting situations. The lens is currently the smallest and lightest in its class*, with a maximum diameter of 65.4mm, a length of 74.5mm and a weight of 290g*, while maintaining a constant F2.8 aperture.

To keep the weight down, SIGMA has constructed the lens from specially selected materials. The lens barrel is made of TSC (Thermally-Stable-Composite) polycarbonate, which is slim and robust and, most importantly, has a thermal conductivity similar to that of aluminum. This ensures high reliability and smooth operation under changing temperatures. For some internal components, SIGMA made a conscious decision to use metal, as these parts require less material while providing greater strength. As a result, the lens is designed to withstand more intensive use.

Suitable for a wide range of shooting situations

The SIGMA 18-50mm F2.8 DC DN Contemporary has a fast and nearly silent autofocus that makes it recommended for a wide range of photographic applications, including shooting in quiet environments and shooting video and photos that require fast focus tracking. This is achieved by using a stepper motor to drive the focus. Because the lens is small and lightweight, it can be used very flexibly in situations that require high mobility, or when shooting from hard-to-reach shooting positions, gimbal shooting, one-man video recording, and vlogging.

A wide range of uses was a priority in the development of the lens, and SIGMA has chosen a design with a closest focusing distance of 12.1cm and a maximum magnification of f/2.8**, making it ideal for close-up shooting

Together with the extremely compact full-frame SIGMA fp camera, this results in a total weight of just 712g - so the lens can also serve as a "back-up" on a full-frame camera in crop mode if, for example, the weight of the equipment needs to be minimized

The 18-50mm F2.8 DC DN Contemporary, which combines compact dimensions, light weight, high performance, and fast speed, handles a wide range of tasks primarily with entry-level mirrorless models, both in photography and video recording, but also with full-frame cameras
