High speed of F2.8 and outstanding image quality

The SIGMA 18-50mm F2.8 DC DN Contemporary covers the focal length range between 27 and 75mm (equivalent to 35mm format) - with a continuous speed of F2.8. This makes it ideal for portraits and close-ups where you want to crop the subject against a blurred background that does not distract from the subject in focus thanks to the attractive, soft bokeh

.

With three high-precision, bright-pressed aspherical lenses and a reduction in the total number of optical elements, the lens achieves outstanding image quality with a low weight. The in-camera correction of optical disturbances also helps to eliminate aberrations such as distortion and vignetting. This performance is made possible by the advanced lens development technology at SIGMA's sole manufacturing facility in Aizu, Japan, where all SIGMA lenses are produced.

Exceptionally light and compact - ideal for mirrorless cameras

The SIGMA 18-50mm F2.8 DC DN Contemporary is remarkably light and compact, making it the perfect complement to APS-C mirrorless cameras. It is the perfect standard zoom, ideal for everyday use and suitable for a wide range of shooting situations. The lens has a maximum diameter of 69.2mm, a length of 74.5mm and a weight of 300g, while maintaining a constant aperture of F2.8

.

To keep the weight down, SIGMA has constructed the lens from specially selected materials. The lens barrel is made of the polycarbonate TSC (Thermally-Stable-Composite), which is slim and robust and, above all, has a thermal conductivity similar to that of aluminum. This ensures high reliability and smooth operation in changing temperatures. For some internal components, SIGMA deliberately opted for metal, as these parts require less material while being stronger.

This

means that the lens is designed to withstand even intensive use.

Suitable for a wide range of shooting situations

The SIGMA 18-50mm F2.8 DC DN Contemporary has a fast and almost silent autofocus, which makes it suitable for a wide range of photographic applications, including shooting in quiet environments and taking videos and photos that require fast focus tracking. This is achieved by using a stepper motor to drive the focus. As 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 shots, one-man video recordings and vlogging.

The

lens was developed with a wide range of applications in mind, so SIGMA has chosen a design with a closest focusing distance of 12.1cm and a maximum magnification of 1:2.8**, which makes it ideal for close-up photography

.

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

The specifications for magnification and closest focusing distance apply to the shortest focal length

Special features of the Canon RF mount

Users of the Canon RF mount system can now also use high-performance Sigma

A control algorithm that optimizes the AF drive and communication speed has been specially developed for the Canon RF Mount

.

In addition to high-speed AF, the lens also supports continuous autofocus (Servo AF) and in-camera aberration correction*. The bayonet of the lens is fitted with a rubber lip to prevent the ingress of dust and moisture

*Only in combination with compatible cameras
