Turn the zoom ring to extend the RF 24-50mm lens from the parked position (left) to its ready-for-photography position (right)
BRIAN SAYS… Several Canon lenses are designed to compact down when not in use, and the RF 24-50mm is one such lens. The optical design of these lenses means there is space between the front and rear internal lens groups. To reduce the lens’s packed size, the parked position closes the gap, shortening the lens. The zoom ring needs to be turned to the normal zoom range to clear the message from the camera screen.
