I would like to try some off camera flash and intend buying a wireless flash trigger and at least one receiver (maybe 2 for when I get another flash) and I am confused after looking at them all ........ mainly the Youngnuo RF602. My questions are -
1...... Do they have to be compatable with my camera model ( 500D) ?
2...... Do they also have to be compatable with my current flash ( 430EXII) ?
3...... If so, some sites say it will work with the 430EX. What about the 430 EXII ?
