Sigma brings Fast Zoom 18-50mm F2.8 DC DN for APS-C Cameras

Sigma is bringing its first zoom lens, especially for mirrorless cameras with APS-C sensors with a usable zoom range of 27–75mm equivalent to small images. Sigma 18-50mm F2.8 DC DN contemporary lens makes it suitable for a wide range of photo and video recordings, ranging from landscape, portrait, and street photography to architectural recordings and reportage.

Sigma 18-50mm F2.8 DC DN Contemporary Lens

With an image scale of up to 1: 2.8 (with the shortest focal length), it can also be used for close-up photography up to a focus limit of 12.1 cm. The largest aperture of F2.8 not only enables free-hand shots even in poor lighting conditions but can also provide effective exposure of the subject by playing with a shallow depth of field.

The autofocus is very fast and quiet thanks to the stepper motor drive. It is particularly useful for photos and video recordings of fast-moving subjects such as children and animals. Thanks to its low weight of just 290g and its compact dimensions, it is a perfect choice as an “always-on lens” that can cope with a wide range of shooting situations. It can also be used as a “back-up lens” on a full-frame camera in APS-C mode.

The Sigma 18-50mm F2.8 DC DN contemporary lens covers the focal length range between 27 and 75mm (equivalent to 35mm format) with a continuous light intensity of F2.8. It makes it ideal if you want to cut out the subject in portrait and close-up shots against a blurred background that does not distract from the sharply depicted subject due to the attractive, soft bokeh. With three molded aspheres and a reduction in the total number of optical elements, the lens achieves an outstanding image quality with low weight. The camera-internal correction of optical disturbances also helps to eliminate imaging errors such as distortion and vignetting.

The contemporary lens is very light and compact and therefore, the perfect addition to mirrorless APS-C cameras. As a standard zoom, it can cope with everyday life and a variety of shooting situations. The lens is currently the smallest and lightest in its class, with a maximum diameter of 65.4 mm, a length of 74.5 mm, and a weight of 290 g (in the version with L-mount), with a constant aperture of F2.8, retains.

To keep the weight low, Sigma designed the lens from specially selected materials. The lens barrel is made of TSC (Thermally Stable-Composite) polycarbonate, which is slim, robust, and above all, has a thermal conductivity similar to that of aluminum. According to Sigma, this ensures a high level of reliability and smooth functioning with changing temperatures. Sigma made a conscious decision to use metal for some internal components, as these parts require less material and are more rigid. According to Sigma, the lens is designed to withstand even more intensive use.

The new Sigma lens has fast and almost silent autofocus, which makes it suitable for recording in quiet surroundings as well as for recording videos and photos that require fast focus tracking. It is achieved by using a stepper motor to drive the focus. Since the lens is small and light, it can be used well for recordings from difficult to access positions, for gimbal recordings, one-man video recordings, and vlogging. With a close-up limit of 12.1 cm and a maximum reproduction ratio of 1: 2.8 (with the shortest focal length), the lens is also well suited for close-ups.
