EOSInfo is the long-awaited successor to the 40DShutterCount utility.  It displays useful information about your Canon EOS DSLR, including the shutter count (on models for which the shutter count property is available). 

EOSInfo improves upon the older utility in the following ways:

• Packaged with an installer, so installation involves downloading and running the installation program instead of mucking about in Windows Explorer
  
• Recognizes cameras attached and/or powered on either before or after the software is started
• Displays the camera's body id, firmware version, date/time, and owner/artist/copyright information 
• Updates the shutter counter in real time when shooting tethered (except for the 5DMkII, which still needs to be power cycled for the shutter counter to update)
