Should I not be able to control a 430EX (not the II) model as well with a 580EX II as with a 580EX? I bought a "gently used, 100% functional" 580EX II on eBay (first mistake, I guess). I cannot get it to trigger my 430 as slave. I borrowed a 580EX (old style), and it has no problems. I've experimented with all the settings, channels match, 580 II is in Master, etc., etc., but no dice. So, just making sure that old 430 and new 580 models should play together nicely. Thanks.
