Choose the role played by the depth-of-field
preview button, either by itself (
Preview
button press) or when used in combination
with the command dials (
Preview +
command dials). The options available are
the same as for
Fn button press (0 293) and
Fn button + dials (0 295), except that the
default option for
Preview button press is Preview and the
default setting for
Preview + command dials is None.
Choose the role played by the AE-L/AF-L
button, either by itself (
AE-L/AF-L button
press) or when used in combination with the
command dials (
AE-L/AF-L + command
dials). The options available for AE-L/AF-L
button press are the same as for Fn button
press (0 293), except that AE-L/AF-L button press defaults to AE/
AF lock and has an additional AF-ON option (if this option is
selected, pressing the AE-L/AF-L button has the same effect as
pressing the
B button to initiate autofocus; this option can not
be used in combination with
AE-L/AF-L + command dials). The
options available for
AE-L/AF-L + command dials are the same as
for
Fn button + dials (0 295), except that AE-L/AF-L + command
dials defaults to None and lacks 1 step spd/aperture option.
