to a selected aperture by pressing the aperture stop-down
button. Pressing the button again fully opens the aperture.
Whether the aperture is stopped down or not, check the camera
viewfinder, or check the diaphragm from the front of the lens.

down to a selected aperture automatically by pressing the

the camera is turned off (including using auto meter off
function) after stopping down the lens aperture by pressing the
aperture stopdown button, the aperture stop-down is cancelled
and the diaphragm blades fully open to the maximum aperture.
