I read the stuff from Nikon and started to download but for some reason did not do it then. Then, I forgot about the upgrade and did not download it to my camera. You asked if the upgrade was needed..new camera, etc. I said it would do just like it does now..so does mine and that seems fine so I have not been in any hurry since then to upgrade the firmware. So, that is why this thread..does the upgrade really make a difference?
