I was out shooting with my D300s this morning and encountered a problem. When I take a picture the camera displays the “Err” error message and the picture comes out massively overexposed. After doing a little checking it appears that the mechanism that stops down the lens is not working. I get the same error message when I press the DOF preview button and the stopping down of the lens again does not work. I checked to make sure it was not the lens (good thing since I was shooting with the 500mm F4). I’m planning to send it to Nikon for repair. Has anyone else encountered this problem? How long should I expect Nikon to take to fix it?
Thanks for your help.
