Number of shots taken by Nikon D80 camera

The Nikon D80 camera contains a EXIF tag value that counts the number shots taken

Tag (hex) Tag (dec) IFD Key Type Tag description
0x00a7 167 Makernote Exif.Nikon3.ShutterCount Long Number of shots taken by camera

This can be extracted by running the following command

exiv2 -pt picturename.JPG
...
Exif.Nikon3.ShutterCount                     Long        1  5263

This example shows that there have been 5263 shots taken.

I guess this EXIF tag exists on Nikon D40x, D60 and D70 also, but this is not verified.
