Description

ABSTRACT:
A camera system for communicating data between a micro computer in a camera body and a macro lens mounted to the camera body. A K value of an automatic focusing drive pulse coefficient is transmitted from the macro lens to the micro computer of the camera body. The macro lens includes a position detecting device for detecting one of a plurality of divided photographing distance steps that correspond to the photographing distance of the macro lens. A K value outputting device outputs a K value at a specific photographing distance of the macro lens, while an arithmetic operating device calculates the K value in a macro-photographing position of the macro lens in accordance with data of the position detecting device and the K value outputting device.
