Breathtaking versatility
A large zoom lens with F2.8 brightness that never needs to be taken off your camera.
This exceptionally small, lightweight and high brightness standard zoom lens for mirrorless cameras with image cropping is the epitome of lenses.
Sigma's first zoom lens for APS-C sensor mirrorless systems delivers the focal length of 27-75mm lenses commonly found on full-frame cameras, making it ideal for a range of photographic and video applications from landscapes, portraits and street photography to architectural and event photography. The magnification ratio of 1:2.8 also makes it suitable for macro-style photography, with a minimum object distance of just 12.1 cm. The F2.8 brightness makes it easier to shoot tripod-free in low light, and the shallow depth of field helps to make photos more effective.
Automatic focusing is exceptionally fast and quiet thanks to the stepping motor, which is particularly useful when shooting video, animals, children or other fast-moving subjects. The lens is exceptionally small and lightweight (less than 300g), making it ideal as a first interchangeable lens or as a second lens on full-frame bodies for a wide variety of photographic tasks.
High F2.8 brightness and outstanding image quality
The Sigma 18-50mm F2.8 DC DN | Contemporary covers the 27mm to 75mm range common on small film cameras, while offering F2.8 aperture throughout the zoom range. This makes it easy to blur the background, which comes in handy when shooting spectacular portraits or close-ups. The bokeh is soft and pleasing, so it doesn't distract the viewer from the subject.
The lens' three large precision-molded glass aspherical elements in a minimized lens replacement system guarantee outstanding optical quality without unnecessary weight, while in-camera corrections effectively correct optical defects such as geometric distortion or edge darkening.
Exceptionally compact and lightweight frame ideal for mirrorless cameras
The Sigma 18-50mm F2.8 DC DN | Contemporary is remarkably compact and well suited to mirrorless APS-C sensor cameras. This makes it a perfect companion, ideal for everyday tasks. It's the smallest and lightest lens in its class, with a maximum diameter of φ65.4 mm, a length of 74.5 mm and a weight of 290 g, yet it can deliver F2.8 aperture at full focal lengths.
To make the lens as lightweight as possible, Sigma engineers built the body from carefully selected materials. For the tube, they chose a polycarbonate called Thermally Stable Composite (TSC), which is filigree, robust and, most importantly, has the same thermal expansion properties as aluminium. This ensures stable performance and good usability even when shooting at varying temperatures. The fact that some internal components are made of metal allows them to be thinner yet more robust, so the lens can withstand frequent, heavy use.
Supports a wide variety of shooting situations
The Sigma 18-50mm F2.8 DC DN | Contemporary uses a faster and almost completely silent AF system, making the lens suitable for use in a range of photographic areas, including quiet locations, video recording and shooting fast-moving subjects. This is made possible by the stepping motor used within the AF mechanism. Because it is small and lightweight, it is well suited for situations requiring high mobility such as handheld photography, video shooting with a gimbal, one-on-one videography or vlogging.
About the minimum object distance
Sigma has designed the lens with a minimum focal length of 12.1 cm and a maximum magnification of 1:2.8* to make it as versatile as possible in a wide range of shooting conditions and ideal for close-ups.
*Both the smallest object distance and the highest magnification are available at the widest angle of view. Remove the lens hood when you plan to shoot at the maximum angle of view (minimum focal length) and the smallest subject distance.
