Tonight I just read about a problem that a MaxPreps photographer recently encountered. I quote: "I was shooting a couple of soccer matches tonight with my D4 on the 400 mm and when I needed to change lenses at the end for the awards ceremony, I couldn't dismount the lens. Anybody had this problem and been able to fix it without sending it in?"
I have the same lens and camera combination and sure would like to hear from anyone else who could have encountered this problem. Thanks
