Why is there a delay between the time I press the shutter button and when the camera beeps?

• If you have installed optional expanded memory, you may notice a delay between the time you press the shutter button and when the camera beeps. You can reduce this delay by pressing the button down halfway, holding it as long as necessary, and then pressing it down the rest of the way when you are ready to take the picture. The reason for this two-step shutter is to save battery power. After a picture is taken, compressed, and written to memory, the Sparc CPU shuts down to save the battery's power. When the shutter button is pressed halfway, the Sparc wakes up and stays in the ready state until the user presses the shutter button the rest of the way. Besides the delay in waking the Sparc, there is a variable delay which occurs prior to the Sparc being in the ready state. This delay is dependent on the amount of free flash memory.
