7d & ishoot triggers
Hi, At the budget end of the trigger market, I would avoid the c433MHz freq triggers as the 2.4 GHz triggers are generally more reliable. Next check for latency. If you want to maintain your max sync speed option, you need low latency triggers.
Currently I'd look carefully at Ojecoco AKA Commlite triggers, but perhaps not their 550 type.
