4) SPEED : Sets auto iris speed (Lens Type is DC mode).
Set in a range of 1 to 15 where hunting is not produced. Press R to increase and L
to decrease the setting.
Simultaneously press R and L for about 2 seconds to set to 8.
5) OPEN Limit : (Lens Type is DC mode.)
Set to where the camera recognizes the iris is fully open. Observe the iris and

open. Press R to increase and L to decrease the setting. Press the L and R buttons

Since picture quality deteriorates as the iris approaches fully open, Open Limit can
be set to where this does not occur.
