Canon SCOOPIC 16M - Manual (Page 54)

When you wish to zoom up on a subject and put it into
the center of the viewfinder, set the focal length at
75mm (3”), position the subject in the center of the
viewfinder, return it to the short focal length side, and
then zoom up once more on the subject and shoot.
On the contrary, if the subject is positioned in the
center with the focal length set on the short side, the
slight aberration at that time will be expanded when the
lens is zoomed up to form a zooming aberration.
