ZK lenses correspond with the KA standard. Additionally to the mechanic aperture coupling the lenses are equipped with an electronic contact pin. Furthermore, the aperture ring can be locked to the automatic mode (green “A”). Thus, all different exposure control settings (time, aperture and program mode) are possible with these camera models.
