Abstract
An interchangeable camera lens includes a main barrel for holding a diaphragm and optical elements, wherein the optical elements define an optical axis (A), a diaphragm rotating ring, rotatable by way of a rotational movement about the optical axis (A), for setting the diaphragm to different f-number values, and a click-stop device. The click-stop device interacts with the diaphragm rotating ring in such a way that the click-stop device is effective in an active work position and the diaphragm rotating ring is therefore rotatable in a stepped manner. The click-stop device is ineffective in an inactive work position and the diaphragm rotating ring is therefore continuously rotatable, wherein the click-stop device comprises a click-stop element seated on a pressure element. The click-stop element is pressable into click-stop grooves by the pressure of the pressure element to enable a step-wise rotation of the diaphragm rotating ring in the active work position. Means are provided for selectively activating and deactivating the click-stop device, wherein the means comprise a movement element which is arranged between the pressure element and the click-stop element and a switching elem…
