Sigma announces world’s smallest and lightest fast-aperture zoom lens for APS-C mirrorless cameras

Sigma’s first APS-C size mirrorless zoom lens 18-50mm F2.8 DC DN | C, has a versatile full-frame equivalent zoom range of 27-75mm, which makes it ideal for a wide range of photo and video applications including landscapes, portraits, street photography, architecture and events. The lens’ three high-precision glass-molded aspherical elements coupled with the minimization of the total number of elements yields superb optical quality without excessive weight, and the use of in-camera aberration correction further eliminates optical imperfections such as distortion and vignetting.

Sigma’s first APS-C size mirrorless zoom lens 18-50mm F2.8 DC DN | C can also be used for macro-style close-up photography owing to its maximum magnification of 1:2.8, which allows a minimum focusing distance of just 12.1cm. In terms of its bright F2.8 aperture, it makes for easier hand-held low-light shooting and provides a shallow depth-of-field for high-impact results.

Autofocus is exceptionally fast and quiet thanks to the stepping motor, which can be particularly useful when shooting video, or fast-moving subjects such as children and animals. The lens’ exceptionally small and light form factor that weighs less than 300g makes it perfect as a first interchangeable lens for various shooting situations, as well as an ultra-compact option for full-frame bodies.

shooting situations, as well as an ultra-compact option for full-frame bodies.

To keep the lens as light as possible, SIGMA constructed the body from carefully selected materials. A polycarbonate called Thermally Stable Composite (TSC) was used for the construction of the barrel, which is sleek, robust, and importantly has a thermal conductivity close to that of aluminium. Sigma Made in Japan craftsmanship lens 18-50mm F2.8 DC DN | C is available for approximately $549.00.
