I recently realised whenever i remove my lens hood from my d80 kit, there will be a flashing F-- in the lcd...after reading the manual it seems that the camera is unable to detect the lens. What i did was to unlock and lock the lens again. This happens also when i take the camera out of the bag by holding onto the lens (might not be a good thing to do).
Is this normal? Or should i bring it to NSC for a check...i suspect either the lens or camera contact is loose.
