Im just talking to Fuji about getting it cleaned so your be okay. Any shot you upload has to have me as photographer though, nobody will know the difference
The software that came with the camera contained a program called Exif Viewer (Something like that) that will display thumbnails of all the shots. Right click on an individual image and it displays an information tab that lists, focal length, shutter speed, aperture so on and so on. Did you not get the same program with your S1? If not let me know and I will send you a copy.
504mm=756mm in old fashioned
film style for those interested
