Nikon D300S- sticking release mode dial?
I have an intermittant problem with my 2 year old Nikon D300S: The release mode dial sticks, even with the dial lock release firmly pressed. When this happens I am unable to rotate the dial from its usual "Mup" setting to any other position. When the dial does eventually move (after considerable force), it does not move smoothly; it sticks. Temperature and moisture does not seem to be factor. The camera has not been exposed to dust or sand. Has anyone had the same problem? Does anyone have any suggestions?
