I am looking for a good wireless transmitter to control my Canon 580EX, and then let that trigger my White Lightening WL 5000 as a slave.
What are my choices? What luck are others having doing this?
I have looked at the Smith - Victor RTK-4 and the Canon ST-E2, which will work better for this and still work as ETTL?
Looks like the SV is much cheaper ($84 @B&H vs. $220 for Canon).
