Operating the revolving adapter
When the horizontal format mark of the
revolving adapter is facing upward, a horizontal
photo will result. For a vertical photograph, turn
the revolving adapter clockwise until it stops.
To change from vertical to horizontal, turn the
revolving adapter counterclockwise.
In either case, be sure to turn the adapter a
full until it clicks and stops. If the adapter is
stopped midway, the shutter release button
cannot be pressed.
Do NOT turn the revolving adapter while
l
the shutter release button is being pressed.
Especially, when a cable release or a self-
timer is used, and adjustment of the release
tip is improper, the shutter release button
will remain depressed after the shutter is
released. Please note!
