Separate flash unit connection and use
Separate flash units can be electrically connected either by way of
the hot shoe accessory holder (see previous warnings) on the top
of the viewfinder or via a cord to the PC connection port on the
le hand side of the camera body. Slave unit switches/ transmitters
can also be connected similarly dependant on unit (see specific
user manuals for details).
Keep the plastic safety cover in place in the hot shoe when not
in use.
Flash measure of separate flash unit
You can measure the effect of an attached flash unit (with PC
connected flash units and SCA3902 compatible flash units set to
M mode), where the camera acts much as a flash meter would. By
choosing ‘Flash measure’, a trial exposure is made with the aux-
iliary shutter still in place which therefore prevents film frames
from being used. e aperture setting can be adjusted and more
trial exposures made until the information on the grip LCD is
satisfactory.
To use flash measure:
1) Press the FLASH button on the grip to access the flash option
screen.
2) Turn the rear control wheel until Flash measure appears.
3) Press Save (DRIVE button) to access the flash exposure
screen.
4) Make preliminary required aperture setting by turning the front
control wheel.
5) Press the AE-L button. The camera will close the aperture,
raise the mirror and fire the flash. Light reflected from the flash
lit subject will be reflected off a white spot on the auxiliary
shutter to the meter sensor.
6) Deviations from a normal exposure are displayed as differ-
ences in EV on the grip LCD and the viewfinder LCD. If ‘high’
or ‘low’ appears, change the aperture accordingly and make
a new test reading.
Change the aperture until Diff EV: 0 appears, or the desired
amount of deviation from the normal exposure.
Diff EV: Low signifies more than 2 EV under
Diff EV: High signifies more than 2 EV over
