✦ The On/Off button. Press the
on/off button for about a half-
second to turn the SB-600 on
or off.
✦ The Flash button. Press this but-
ton to test fire the SB-600 to check
for output.
✦ The Zoom button. Pressing this
button changes the zoom of the
flash head to adjust for different
focal length lenses. It allows cover-
age for 24mm to 85mm lenses.
14mm coverage is achieved with
the built-in wide angle diffuser.
✦ The +/- buttons. The +/- buttons
are used to change the values and
settings on the SB-600 LCD screen.
Depending on the flash mode the
values and settings will be different.
• TTL/TTL BL. The +/- buttons
allow you to set the flash com-
pensation of the Speedlight to
underexpose or overexpose
from the camera’s TTL reading.
The flash compensation can be
set +/- 3 stops in
1
⁄3 stop
increments.
• M. The +/- buttons are used to
set the flash exposure manually
from
1
⁄1 to
1
⁄64. These settings are
also adjustable in
1
⁄3 stop
increments.
• CSM. When in the custom set-
tings mode, the +/- buttons are
used to cycle through the differ-
ent custom settings.
The Custom Settings Menu is
covered in detail in Chapter 2
Setting up the SB-800 and SB-
600.
✦ The Mode button. The mode but-
ton allows you to switch between
the available flash modes. The
modes available with the SB-600
are:
• TTL BL – i-TTL balanced fill
flash. The exposure is deter-
mined by the camera and
matched with the ambient light.
• TTL – i-TTL flash. The expo-
sure is determined by the cam-
era to sufficiently illuminate the
subject that is focused on.
• M – full manual mode. You
determine the flash power.
Depending on which camera
and lens you are using, all of
the SB-600 flash modes may or
may not be available.
In addition to the standard buttons on the
back of the SB-600 Speedlight, there are
some functions that can only be accessed
by pressing two buttons at the same time:
✦ Zoom and Mode. When the Zoom
and Mode buttons are pressed
simultaneously, the underexposure
value from the TTL reading is dis-
played.
✦ Mode and On/Off. Pressing Mode
and the On/Off button together
resets the SB-600 settings to fac-
tory default. You may need to do
this if you’ve changed the settings
and have forgotten what changes
you’ve made.
