A good friend of mine (from Israel) is offering for sale a Nikon D600 body with a damaged lens mount - it somehow broke off along with a small part of the camera body.
The damage occurred due to a very light impact to the 70-200mm lens while it was attached to the camera. Lens did not suffer:)
Camera & sensor itself is fully functional. US Nikon refused to repair this damage stating that "camera is beyond economical repair".
Please let me know if there is any interest to use this as a base for development, and your offer. I have the camera in my possession in NYC.
