Here is the Excel version (.xls) of the D800 Configuration & Settings Spreadsheet I posted a few days ago.
This is now the FULL RELEASE version - I am attaching both the Excel and updated Apple iWork Numbers versions.
As I have not yet had my hands on the camera (still waiting for my pre-order to arrive), I have set most of the settings in the spreadsheets to standard Nikon default settings, but you can play around with them to set the camera up to suit your shooting preferences.
Please read the Instructions on the first worksheet "Introduction" to get a feel of how to use this tool.
I hope it proves helpful! I would welcome any comments or any problems that you may find with it.
MODERATOR'S UPDATE WITH LATEST FILE VERSIONS AS OF 05-08-2012:
I have also attached a Non-Interactive .pdf version so you can see what it looks like (the settings shown in the cells in this version are of course only illustrative of the selection(s) that had been made when this "snapshot" was taken.
I would also like to acknowledge the terrific help that Eric Bowles and Ernesto Santos have given me in getting the orginal Numbers version of this tool to work in Excel, and for their great advice generally. Thank you gentlemen!
