Abstract: A camera system of a mobile device includes: a sensor module disposed in a first body connected to a rotation member of the mobile device; and a lens module disposed in a second body connected to the rotation member. When the first body and the second body are rotated with respect to the rotation member to overlap each other, optical axes of the sensor module and the lens module correspond to each other and are operated as a common camera system, and the common camera system provides a first photographing mode and a second photographing mode with different viewing angles based on two focuses generated by a first geometry phase lens included in the lens module.
