Aha! Got it! Thanks for clearing that out for me! Also, all this time for some odd reason I had in my head that the 7d didnt have a pop up flash. Clearly it has one.
If I use the 430 EX II as the master and use one from Yongnuo as a remote slave will be able to do a high speed sync? (Provided Yongnuo flash units support high speed sync configuration). Any particular model from Yongnuo you (or anyone) recommend that I can consider for such a setup? I hope I made sense. I am looking at these eneloops, they the right ones I need I am hoping?
No you will not be able to use 430 EX II as a master ... it can only be used as a slave.
Using or not using any Yongnuo trigger will not make 430 EX II to do high speed sync ... any such attempt will most likely burn out your flash rendering it useless.
Currently 580 & 600 are the only 2 Speedlites from Canon that can do hgh speed sync
Those eneloops ar plenty good for 430 EX II
