The Sony Cyber-shot DSC-RX100 II Digital Camera is a compact point-and-shoot camera that features a large 20.2 megapixel 1" Exmor R CMOS sensor to produce high resolution still imagery and full HD 1080i/p video. This sensor's design utilizes backside-illuminated technology to improve clarity and image quality when working in dimly-lit conditions as well as increase the sensitivity to an expandable ISO 12800. Benefitting the performance of this sensor is the BIONZ image processor, which helps to produce images with smooth quality and gradations as well as provide expedited performance throughout all aspects of the camera. The built-in Carl Zeiss Vario-Sonnar T* 10.4-37.1mm f/1.8-4.9 lens provides a 35mm-equivalent focal length range of 28-100mm, covering wide-angle to portrait-length perspectives to suit working in a wide variety of environments. On the wide end of the lens, the bright maximum f/1.8 aperture benefits working in low lighting as well as aiding in controlling focus. Optical SteadyShot image stabilization is also available to help minimize the appearance of camera shake when working in dimly-lit conditions and with greater zoom magnifications. The lens also features a Carl Zeiss T* anti-reflective coating, which helps to reduce surface reflections, lens flare, and ghosting in order to produce imagery that is rich in contrast and clarity.
