The camera is likely to FRY (comments from John H?). Plus, it won't
work.
There is a way to do what you are seeking to do. It was scienced out
by our very own John Lind, and if I remember, it goes like this:
1.- Set camera on AUTO mode. Set ASA for correct film speed (or
your own E.I.). EV compensation dial set at ZERO.
2.- Mount flash on camera, LEAVE UNIT TURNED OFF.
3.- Frame, focus and with the flash still OFF, choose an aperture
that gives you 1/60th.
4.- Turn flash unit ON to TTL AUTO mode. This locks the shutter
speed to 1/60th, and gives you A) Proper synch speed, and B)
your ambient exposure.
5.- Now turn your EV compensation dial --- without lifting it
which would change your ASA --- clockwise to anywhere from
-2/3 to -2, depending on the intensity of the fill desired.
Experiment with this part, because it takes experience to
be able to judge this. Conversely, you can "bracket fill"
easily with this method.
IMPORTANT: This, like all systems relying on reflected readings,
is not a substitute for using your head. If you're
fill-flashing a white cat against black dirt, or a
black one against snow, you will have problems unless
you know what you are doing. Experiment carefully before
using this on an important shot. Oh, if the ambient light
changes, you will have to repeat the procedure. Also,
don't forget to reset the compensation dial to ZERO
when you are done !
This should help Dirk...
