Controlling Exposure
2. Rotate the Main-Command dial to select buLb, and rotate the
Sub-Command dial to set the aperture.
IMPORTANT: If buLb is selected in Manual Exposure mode and you
change to Shutter-Priority Auto Exposure mode without
cancelling buLb, buLb blinks and the shutter locks.
Select a shutter speed other than buLb by rotating the
Main-Command dial.
3. Compose the picture, focus, and capture the image.
The shutter remains open as long as you fully press the Shutter
Release button.
