Fine. So it is a small market. The question is what does it take to get it
to work? Is it possible to modify a SCA-321 somehow to get the Metz unit
to fire in HSS mode? Is this an impossible dream?
If I understand Metz' SCA system correctly, I believe HSS requires the
additional flash head interface contacts present in an SCA3000 or SCA3002
series module. If it does, it would require modifying one of those modules
with the proper number of contacts in the correct locations. You'd have to
reverse engineer an SCA-321, implement that in a suitable SCA-3000 module,
then figure out how the HSS is controlled, design the necessary additional
circuitry for it and add that too. AFIK there's zero documentation
floating around about the Metz' SCA modules and the interface with the
flash heads. I started to reverse engineer an SCA-321 once, and eventually
threw in the towel. It's not straightforward. There *is* some circuitry
beyond just wires inside it, and IIRC it uses much more than three contacts
between module and flash head to translate an OM Shoe 4 to Metz' SCA-300
interface with their flash heads.
Ugh! My brain hurts just thinking about it.
