A zoom lens includes, in order from the object side to the image side, a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having a negative refractive power, and a rear lens group including a plurality of lens units and having a positive refractive power as a whole. The device includes a first processing module; a second processing module connected in its inter-chip path with the first processing module; and an application processor for controlling the first processing module to transmit an IMSI to the second processing module when a traffic handover event from a first mode to a second mode occurs. Metal is deposited to surround the exposed negative.
