Hello, just a noob question for the guapings of DPP--I recently got a Sigma EF 500 ST flash, which is TTL II capable (for Canon). But I'm planning to use this also as a Slave, and read there are compatibility problems with currently available RF wireless triggers. It has no PC chord synch jack, so the wired option is out. What's the recommended method to trigger this flash off-cam?I tried a shoe mount-optical trigger combo, and test fired a strobe, but it would not trigger the flash at all. By the way, budget is a little tight, and would love to get those Pocket Wizards triggers para wala nang problema, but at $295 ea, it's really not the best option at the moment.

Any suggestion and help would greatly be appreciated. Thanks in advance!

try the gadget infinity radio triggers. its around P2,000

Thanks aldrich, I came across this in the other threads,looks interesting. Wish there was a tutorial on it for Sigma flashes. Anyhow, I'll try it out for starters and give feedback when I'm through...
