The invention relates first to a camera module for a microscope. The camera module comprises an optical interface for inserting the camera module into an imaging beam path of the microscope, which imaging beam path images a nominal intermediate image. Furthermore, the camera module comprises an electronic image converter and a functional element for changing an intermediate image plane, which functional element is arranged in a beam path of the camera module between the optical interface and the image converter. The camera module also comprises a first optical assembly having an optical power, which first optical assembly is arranged in the beam path between the optical interface and the image converter. According to the invention, a distance between the functional element and the optical interface along the beam path or a distance between the first optical assembly and the optical interface along the beam path can be changed. The invention further relates to a method for operating the camera module.
