Leica Digilux3 is the first Digilux camera with an interchangeable lens and therefore forms the basis for the Leica D system, a completely independent digital SLR system. The clear design of the camera housing and the operating concept of the Digilux are in keeping with the best Leica tradition. The shutter speed, focal length, aperture and focus can be set by hand on the camera and the lens–a fast, precise and creative solution in comparison with conventional SLR cameras.
