100 Menu Guide
If Sub-command dial is selected, aperture can only be
adjusted with the sub-command dial (or with the main
command dial if On is selected for Change main/sub >
Exposure setting). If Aperture ring is selected, aperture
can only be adjusted with the lens aperture ring and the
camera aperture display will show aperture in increments of
1 EV (aperture for type G and E lenses is still set using the
sub-command dial). Note that regardless of the setting
chosen, the aperture ring must be used to adjust aperture
when a non-CPU lens is attached.
If Off is selected, the multi selector is used to choose the
picture displayed during full-frame playback, highlight
thumbnails, and navigate menus. If On or On (image
review excluded) is selected, the main command dial can
be used to choose the picture displayed during full-frame
playback, move the cursor left or right during thumbnail
playback, and move the menu highlight bar up or down.
The sub-command dial is used in full-frame playback to skip
forward or back according to the option selected for Sub-
dial frame advance and in thumbnail playback to page up
or down. While menus are displayed, rotating the sub-
command dial right displays the sub-menu for the selected
option, while rotating it left displays the previous menu. To
make a selection, press 2 or J. Select On (image review
excluded) to prevent the command dials from being used
for playback during image review.
When On or On (image review excluded) is selected for
Menus and playback, the sub-command dial can be
rotated during full-frame playback to select a folder or to
skip forward or back 10 or 50 frames at a time.
