he SIGMA 18-50mm F2.8 DC DN | Contemporary is SIGMA’s first mirrorless zoom for crop sensor cameras. With a full-frame equivalent focal range of 27-75mm, it combines exceptional versatility with an ultra small and light body, superb build quality and impressive optical performance. It also boasts a large F2.8 constant aperture that is ideal for creating blurry backgrounds, and allowing easier low-light shooting without the need for a tripod. The lens is perfect for a wide range of photo and video applications including landscapes, portraits, street photography, architecture and events, and it can also be used for macro-style close-up photography owing to its maximum magnification of 1:2.8 that allows a minimum focusing distance of just 12.1cm. Autofocus is exceptionally fast and quiet thanks to the lens’ stepping motor, which can be particularly useful for shooting video, or for capturing fast-moving subjects.
