The camera body comprises: a device for inputting the data from the outputting device of the first or second lens attached to the camera body, a device for discriminating the lens type based on whether the inputted data is the first or second data, a device for storing data with respect to the characteristic of the lens belonging to the first lens type, and a processing device for carrying out a process based on the third data when the discriminating device judges the attached lens belongs to the second lens type and controlling it based on the stored data in the storing device when the discriminating device judges the attached lens belongs to the first lens type.
