Through the Viewfinder
The viewfinder contains two frames. The frame on the left is
used when taking pictures at a range of 50 cm (twenty inches)
or more, that on the right when composing photographs for
macro close-up at ranges of 8 – 50 cm (3˝ – 20˝). The point
marked by the
indicator in the center of the viewfinder is
used as the focus point for the autofocus operation. For the
best results when using programmed autofocus, compose your
photographs so that the subject is at the focus point.

Beneath the viewfinder is a “diopter dial,” which allows users
compensate for individual differences in vision by making fine
adjustments to viewfinder focus. Should you find that the view
through the viewfinder is out of focus even when the image in
the color LCD monitor is in focus, adjust viewfinder focus by
turning the diopter dial.
