A great write-up for an obscure process, But the question consumes me, What does the "DUST SHOOT" do? It is given a very prominent place in the ui with that amazing aperture icon. If I had to hazard a guess it is a drop pocket used to discard synced items. coupled with some loadwords that no longer exactly make sense in english(american. I know british has dust bins, does anyone call them dust shoots?) My second thought was to clean the camera sensor, but that makes no sense at all given the device and the era it was in. I mainly mention this because I was laughing at myself for even thinking of it. "Yes we will give an obscure service action only found on professional cameras a beautiful icon, right on the front page of our sync app"
