>Can a canon ex flash unit work at all with nikon prosumer digital cams?
I would *guess* that it could be used in manual exposure mode,
but certainly not in the iTTL mode. Not even the older Nikon flash
units (such as the SB-28) will work TTL with something like the D70.
Which Nikon cameras are you labeling "prosumer"?
Enjoy,
DoN.
