Thank you,  I do know the difference. Very few hand
scanners have a Nikon
 bayonet lens mount on the front... 
    Hmmm...since the CCD is not read at once (it is scanned) and you take
the camera with your hand, I know many Nikon cameras with bayonet lens mount
on the front :o)
    Sorry Tony, I couldn't resist that :oD
