I recently upgraded my D300 to the 1.10 firmware, and after the upgrade my EXIF info seems to be messed up. F-stops consistently show up as 1. (And I'm pretty certain my 18-200 VR does not go to f1, wish it did though!)
Anyone seeing similar problems after a firmware upgrade?
Ok, I figured out what happened here. I'd only upgraded the A firmware to 1.10 and the B firmware was still at 1.0. After I upgraded the B firmware as well to 1.10, the problem no longer exists. (And I presume I now get the full functionality of the upgrade as well!)
I encountered this very same problem today after ugrading the firmware. I traced the problem to an easy-to-miss detail in the upgrade instructions: firmware A and firmware B must be installed individually. Copy A to the CF card, then follow the upgrade instructions. Delete the A file, then copy the B file and repeat the same process as before.
