The RX100 model compact camera, which went on the market in 2012, combined a 1.0"-type CMOS sensor with a Zeiss Vario-Sonnar T lens to deliver picture quality that rivaled interchangeable lens cameras. Since that time, successive models (RX100M2 through RX100M7) have retained the design while catering to changing user needs with various additional features such as a pop-up viewfinder and a 24-200mm zoom lens. These models are all currently available on the market. Maintaining the same design and building it out into a series of high-performance successors has created brand value out of the product design itself.
