In a word, no.
In a paragraph, the fastest shutter speed for flash is 1/60 sec.(unless you
have a camera using a vertical shutter). At speeds below 1/60, the first
curtain moves across the shutter opening at a constant speed. At a set time
interval, the second curtain follows the first curtain. At speeds higher
than 1/60, the full width of the shutter opening is no longer available. At
speeds higher than 1/60, the curtains are travelling at the same time across
the shutter opening width. The width becomes more narrow as the shutter
speed increases. The best way possible for shutter speeds above 1/60 is to
use a leaf shutter, full sync to 1/500. Time to drag out your Hasselblad!
Or, use one of those new fangled cameras that have vertical shutters that go
to 1/250. Don't trust that new stuff, may not work!

Oops, I wasn't explicit enough. What I should have said was, is there
*another* flash with variable duration that will work with cameras like the
OM-1? (According to the info I've seen the F280 won't sync with the OM-1 at
shutter speeds faster than 1/60th.)
As I use faster films like 400 and 800 outdoors more often than I would have
years ago I'm looking for a way to use flash at higher shutter speeds.
