A camera system comprising a zoom lens is disclosed. The camera system may be used in a measuring apparatus, having a tube-like guide system having a tube body, which defines a tube interior and an optical axis, a sensor module disposed downstream of the guide system and an optical sensor for detecting optical radiation, at least one first carriage which has an optical assembly having at least one optical element and an optical system carrier, is arranged in a manner linearly moveable along the optical axis in the tube interior and is mounted in a manner guided substantially without play through the tube body in a plane perpendicular to the optical axis, and a first drive system for moving the first carriage along the optical axis, said first drive system being decoupled from the guide system.
