As many of you know, the old trick of reading the shutter count does not work with the newer cameras.
Here is what I found in other forums:
camera is switched off
press and hold menu button
switch on camera
release and press again menu button (you are now in the menu)
go to LCD brightness (Setup menu, 3rd tab)
go to brightness sliders
press info button
press ok button
press the arrowkeys up, down, left, right
press the shutter
press arrow key right
here we are

Mike
