Canon PowerShot SX730 HS When the camera is turned on, the metal 'leaves" that cover the lens should fully open. They do not. See the attached picture. The picture shows the lens partially open with the metal leaves stuck in a half open position. In this half open position I can fully open the lens cover by lightly nudging the metal leaves. Note that when I turn the camera off, the metal leaves do not fully close and again I need to gently nudge the leaves to get them to close. So how do I fix this? Perhaps there is dirt between the metal leaves, but I am having trouble getting between the leaves to remove potential dirt. Any suggestions?
