I have a basic question about wireless triggers:
I have the following flashes: 580 EX II, 430 EX II. YN-565EX
I bought 4 YN-603 transceivers for the wireless setup. Planning to put one on the camera and 3 on the flashes. This is the item I bought http://www.ebay.com …1438.l2649#ht_9525wt_1346and it comes with 2 × C3 Shutter release cables. I read somewhere that I will need some others cables for 580 EX. Can one of you suggest what exactly I need?
Also it says its compatible with: C3---Canon: 1D/1DS，EOS5D/5D2/50D/40D/30D/20D/10D. Will it work with my 7D?
