I haven't tried myself but I believe that it should work~ Alternatively, you can check the SC offline with some other EXIF tools. For instance, PhotoME is the most popular choice, which can be downloaded here. Just open an original JPEG image produced by any Pentax (now Ricoh) camera and search for the EXIF tag with the string of "shutter count" or something like that. That's it! :-)
