You can download Opanda Exif Viewer from http://www.opanda.com/en/iexif/index.html All you have to do is format a CF card in the camera, take a photo, upload it to your computer and start Exif reader. In the Exif Reader you will OPEN your photo you just took. Way down the amazing list of data you will see a Shutter Releases category which will tell you the approximate number of shutter releases this camera has had. It will be innacurate if the shutter has been replaced or the camera has been into Nikon service prior to you recieving it.
