When you use it in the through-the-lens (TTL) metering mode (which is the way I normally use it), you can set the lens opening to whatever you want it, from wide open to fully stopped down. It is only in the flash's automatic mode (it is using the flash's light sensor) that the lens opening is fixed. This also means that you can put the flash on an extension (or swivel the head up/down/left/right) to use as fill because it's light sensor is not being used in TTL mode. I don't understand the advantage of using anything other than TTL mode, the pentax manual doesn't seem to be too clear on this.
