Hey guys. Some time ago, there was a thread like this asking about those Gadget Infinity PT04M radio triggers, and someone mentioned that Ruby Photo was carrying something slightly better than the Cactus radio triggers (at a higher price).
My question is this: Lets say I want to fire 3 flashes (2x 580EXII, 1x 430EX). Do I have to get 1 trigger + 3 receivers, or will canon infra-red wireless thing still work with 1 master connected to 1 receiver? Meaning this: Radio transmitter on camera hotshoe, 1 transmitter on 580EXII set on master, and this triggers the other 2 flashes set to slave. Is this possible, or do I have to get another 2 extra receivers?
Oh, and a slightly off-topic question here: Where is this Ruby Photo? I searched Peninsular Plaza (and the directory) and still couldn't find the shop..
