Zoom-Lock Capability — To Fix Zoom-Head Position
A predetermined zoom-head position is useful when you
wish to use an AF Nikkor lens or a Nikkor lens having a
built-in CPU interchangeably with another type. It also pro-
vides flexibility when using lenses of different focal lengths
in rapid succession.
1
Press and buttons simultaneously for a few
seconds until indication starts blinking.
2
Next, press button only to set desired zoom-head
position. This position remains locked as long as the
indication continues blinking.
3
To unlock, press the same buttons simultaneously for a
few seconds until the indication stops blinking or
totally disappears.
Set Up and Practice
Trouble With Wide Flash Adapter
In certain situations, the zoom head
may lock at the 20mm position
(adapter does not return to original
position). If this happens, perform fol-
lowing operation.
Although the adjusted zoom-head
position and/or indication will blink if
the wide flash adapter is stored in its
original place, this does not affect nor-
mal flash operation.
1
Press and buttons
simultaneously for a few seconds
until the previously set number and the
indication start blinking.
2
Press only button to set your
desired zoom-head position.
To resume automatic adjustment with
certain camera/lens combinations (see
page 30), press button until the
indication above disappears.
Automatic zoom-head position adjustment: F90-
Series/N90, F4-Series, F-801/N8008, or F-801s/
N8008s used with an AF Nikkor lens (including the lat-
est D-Type) or Nikkor lens having a built-in CPU
The SB-25 automatically adjusts the zoom-head position
to provide an angle of coverage that matches the focal
length of the lens in use. For details, see page 30.
