The OM2 won't be able to quench the flash bulb. It would only be able to
shorten the shutter open time. It would seem like the OM2 would trip the
flash then act as if the exposure was just a normal OTF auto exposure. Hmmm
a much more powerful F280 flash ... neat

Yes,
See below, the FP bulbs have a nice long plateau when they burn. The
OM2 has an FP setting that fires the FB ?10msec or so prior to
first curtain though X synch will work with a slow shutter speed. I
have a neat dookicky from John that locks it in place
so I don't have anymore untoward foul ups from the switch becoming
inadvertently altered.
I see replacing these monster FB's cost a pretty penny.
It is promising that Dr. Flash thinks it may work in TTL auto. The GN
does vary with the reflector and shutter speed and I will fire 2 to
three but only really
need to be sure I don't overexpose by much. I will set it up on a
tripod per the previous diagram from JK. He should look NE Mon PM and
may perhaps spot
the ignition.
