Can you power the Sigma from a Quantum unit?  If not what is the
advantage of it over the 420ex that is the same price point and is Canon

There is no HV input to the Sigma.
You would have to use the Bantam battery (6v).

Or the QB1+ or the QB1c. See <http://www.qtm.com/battery/compatibility/sigma.html>.
