Pressing the green button (or AE-L button on the *istDS/DL) stops the lens down to the set aperture, the camera reads the light transmitted and sets the appropriate shutter speed. The lens then opens to full aperture for focussing and closes down to the set aperture when when the shutter is fully pressed.
Note that the camera has to be set on "Manual'. If you select Av, the camera defaults to fully open regardless of the aperture set. I'm not sure if the K2000 operates this way, but it probably does.
