I have not used my Nikon D500 since Christmas--I went to delete the pictures out of it and could not when I told it OK the OK was in red --also tried formatting the card and the same thing happened I formatted the card in another camera and had no problem--by the way the camera was a canon so I know it is not the card--works fine in the Canon
It looks like you got it. If you use the menu you are able to format each card. You must select the card to be formatted.
Great camera, by the way
The focus options are enough to test for a while! I am quite anxious to get Steve Perry's upcoming book on Nikon auto focus systems so I can better utilize my Nikons. Soon! I'm into BIF and need all the advantages I can get!
