The Canon Power Shot S120 Point-and-Shoot Camera is a compact point-and-shoot camera featuring a 12.1 megapixel 1/1.7" high-sensitivity CMOS sensor and DIGIC 6 image processor to produce high quality still imagery and full HD 1080p video with notable low-light quality and sensitivity from ISO 80-12800. The sensor and processor work together to form the Canon HS SYSTEM, which helps to improve the image quality of dimly-lit shots by reducing noise and enhancing the overall clarity. Additionally, the processor offers a range of speed-related assets throughout the camera, including a maximum sustained full-resolution continuous shooting rate of 9.4 fps for over 600 shots as well as a High Speed AF system for maintained sharpness in a variety of shooting conditions.

The built-in Canon 5x optical zoom lens provides a 35mm-equivalent focal length range of 24-120mm, covering wide-angle to telephoto length perspectives. A maximum f/1.8-5.7 aperture contributes to working in low-light conditions and also benefits shallow depth of field and selective focus shooting techniques. Also aiding working in dim conditions is the inclusion of Intelligent IS image stabilization, which automatically utilizes one of six different distinct modes to help minimize the appearance of camera shake depending on shooting conditions.

For live view monitoring, image review, and menu navigation, a large 3.0" 922k-dot touchscreen LCD monitor is integrated into the S120's design and facilitates intuitive navigation along with clear viewing. The touchscreen interface gives way to Touch AF along with other touch-specific camera controls that are ideally-suited to use when recording video. The efficiency of the touchscreen also supports use of the built-in wireless capabilities for instantly sharing imagery from the camera to mobile devices. By using the free Canon CameraWindow app, available for Android and iOS devices, photos and videos can be sent to the device for direct sharing online through the CANON iMAGE GATEWAY.
