Just got a bad new from Nikon repair shop indicate it cost almost $500 to repair this 11 years old lens of 17 - 35mm f2.8. The problem occured when I was playing this len with my D800E on live view. After turned off the live view, 800E and this lens can't perform any auto focus. Try on my other len, 50mm f1.8, and it kills as well. Submit all three items to Nikon factory for repair, D800E and 50mm were fixed under warranty, but this len of 17 - 35mm f2.8 just does not auto focus anymore. Anyone has experience with that and any suggestion would be appreciate. Thanks advance,:smile-new:
