If you want dedicated wireless operation, the Pentax AF360FGZ and
Sigma EF 500 DG Super have been the only two fully compatible units
that support all features on the DS body. The new Pentax AF540FGZ,
due out very soon, will also support those features and have higher
output with swivel head like the Sigma.
I've been wondering about this wireless capability. Does it use
line-of-sight infrared or radio control? Does anyone know the
effective usable range of the wireless feature?
Not sure as I haven't got any of them yet. I believe the wireless
control is done by modulating the main flash at low power. As these
are relatively modest power output anyway, I can't imagine it being
useful for complex setups more than 15' between units.
