There are a couple of cameras that appear to use the Olympus Super FP
technology. One is the Sigma SA-5:
"External flash synchronization: Hot shoe (with X contacts and special
strobe "dedication" contacts) During EF430 Super FP flash mode,
synchronization at all shutter speeds up to 1/4000 second is possible.
"
and the Nikon N90s and dedicated Nikon Speedlight:
"FP High-Speed Sync
Enables flash sync with high shutter
speeds from 1/250 to 1/4000 sec., with
manual exposure control. You can
make fill-flash pictures even with ISO
film that has a high rating, and still
maintain wider aperture settings for
expanded control of depth of field."
Either the Olympus patent ran out, or they are licensing the technology
to these companies.
Be seeing you.
