I agree with this statement. Also, what has not been said is that if Cameta sends this to Nikon and Nikon takes the body apart to get the Tamron lens off, who is going to pay Nikon? I can not see Nikon doing it for free. Cameta did nothing wrong as the lens worked until this occurred. So the bill from Nikon would probably go to the consumer.

Sending the camera body with lens to Tamron might not work either as I would not want a Tamron Tech taking my Nikon body completely apart to get the lens off.

What a dilemma. Well I hope we find out the outcome of this situation and best of luck on the resolution to the OP.

Hi all. Was on vacation and this problem developed suddenly. Previous photo (observation point on Mauna Kea on Hawaii and yes, it is beautiful there) was fine. However the next shot everything went nuts. Could barely see the image through the viewfinder, could only see 1 focus point, and when I went to change the lens, it would only turn ~ 1/4" before it stopped and would not go any further to remove it. When I turned it back to reingage, it locked in fine, but the problems persist (low light, only 1 focus point, and cannot remove the lens). Autofocus, exposure are all OK, but the lens won't come off and viewing an image is almost impossible.
I called Tamron and while they said they would certainly take care of the lens (warranty), they would prefer it was off the body since they are not responsible for that. Would prefer not having to send the camera and lens to Nikon since they also will not take responsibility for the lens. I did call Cameta ( I get all my stuff from them) and am waiting to hear back from their tech person but they send all their repairs out. I thought about bringing it down to Mack (I'm in NJ and too far from them) but then lens is still under Tamron warranty.
I don't want to force it off but also don't want to see a repair bill that's bigger than the cost of the camera. So, if anyone has ever experienced a lens-camera problem like this, please let me know what you did to get it off. Any and all suggestions gratefully appreciated.

Hi all. Thanks for the advice. I did call Tamron, Nikon and Cameta. Cameta will try to remove the lens but if they can't, they will send it off to Nikon. Tamron will not touch the D7000 for obvious reasons but will fix the lens. I am not going to try to remove it myself since that would void the Tamron warranty. It could very well be a screw that cam loose, but I'm not going to try to fix it myself since I can damage the lens and camera and have no recourse.
Will let you know the outcome and whose fault it was for all this mess. Bottom line is the camera works now and I want to keep the mechanical problems to a minimum so I'll let the pros handle it from here.
