Anyone have any hints, tips or tricks to removing a Nikon lens off of a Nikon D80 after the camera and lens were dropped on to asphalt. Camera still works and lens still works except not very good in clear focus. Depth of field seems to have taken a hit too. But.... Would like to get lens off and see how much damage there is the camera vs the lens. Lens will not rotate at all when trying to remove from camera even with the release button depressed. Maybe a 0.1" at most Just won't release to allow the lens to be removed. Any hints on how to get the lens off without sending it to Nikon for $$$$$ repair?
