Slot Empty Release Lock

G button ➜ B setup menu
If Release locked is selected, the shutter-release button is only
enabled when a memory card is inserted in the camera.
Selecting Enable release allows the shutter to be released when
no memory card is inserted, although no pictures will be
recorded (they will however be displayed in the monitor in
demo mode).
