I accidentally dropped my lens and for about a week whenever I tried to attach the lens, I would get a message on the camera that said "No lens attached". After messing around with the lens, I found the problem and I can now use the camera. The problem is it isn't adjusting to exposure or auto focusing anymore. I only dropped the lens not the whole camera. Any ideas for how to fix it? I let a friend mess with the camera some too and I don't know what settings they changed.Do I need to get a new lens or send it back to Nikon? Please help. Thanks.
Added (1). I've only had the camera and lens for about 3 or 4 months. This is the first time that it's ever been dropped. I don't have a warranty on it because a relative had gotten it for me and they didn't get the warranty. I do still have all of the papers in the original box, people have told me that they thought there was a limited warranty somewhere in there that you could sign up for online?
