Pentax Q +

The Pentax Q is a mirrorless interchangeable-lens camera made by Pentax and introduced in 2011. As of September 2012, it is the world’s smallest, lightest interchangeable lens digital camera. It uses a 1/2.3" (6.17 x 4.55 mm) back-illuminated sensor CMOS image sensor, which is substantially smaller than the sensors in other interchangeable lens cameras. The camera is equipped with sensor-shift image stabilization technology to improve image quality in low light or when using telephoto lenses.
