I took some photos this morning with the D7000 set in, “Manual”. I then turned the camera off so that I could remove the SD card and upload the images to my iMac. For reasons unknown to me the D7000 would not shut off. I finally had to remove the battery in order to shut the camera down. The lens that I was using was a 16-85mm DX that I have been using for a while.

Was the green memory card write light still on? I had a similar problem when I tried to use a defective new SD card. The camera would not shut off as it got hung trying to write to the card. I had to remove the battery, remove both cards, and then insert them one at a time to figure out which one was bad. Removing the SD cards after the camera had frozen had no effect. Your problem might be completely different but I offer this as food for thought.
