How can I use a 70D with a 580 EX II, 580 EX, and Yongnuo 568 EX II?

[Preston]

I'm trying to figure out how I can use my 70D with a 580 EX II, 580 EX, and Yongnuo 568 EX II simultaneously (with cords). I know I can use two of them at the same time, but the problem is I don't see a PC Sync port on my 70D where I can attach the third one. Is it there but I'm just not seeing it? 

And does anyone have any advice on how I can use all three of these flashes at the same time?

Thanks

There is no PC port on a 70D. The Yongnuo 568 EX II can be used a a slave just like the 580EX or 580EX II.  Why do you want to use a connecting cord?

[Preston]

Thanks for the reply. As for why I want to use connecting cords, it's because it's a lot simpler for a beginner and I haven't gotten to the parts yet in the books I'm reading right now that explain how to do it wirelessly. From what I've read thus far, it seems intimidating so I thought I'd start out with cords and then move on to doing it wirelessly. I wasn't even sure I could use two of them as slaves until you said so too.

You can fire all three flashes at the same time using the pop up flash on your 70D as Master.  Try watching this video to get a better idea on how this works:  https://www.youtube.com/results?search_query=70d+wirelss+flash

You can also search out 60D videos as it works the same way:

Thanks for those links. That helps. I may have to watch them a couple of times though to figure them out fully 🙂

The "groups" thing has be kinda confused, and there may be some other questions I have too once I try setting it up... hopefully not. We'll see...

I don't have the Yongnuo 568 EX II but you can use as many 580 EX II's as you want wireless.  As long as they can "see" each other and they are not too far apart.  It is way easier than PC cords.  But in the event you don't think so, you can buy a PC-hot shoe adapter.  Click me.

The Yongnuo is supposed to be just like the 580 EX II. That's what I've heard from a couple other camera buffs anyway. But the manual is near impossible to decipher as it was written by a non-native English speaker. I'm glad you think wireless is easier than cords though. maybe it won't be so hard to set up wirelessly after all. This is the cord I bought a few days ago: http://www.ebay.com/itm/131279358420?_trksid=p2059210.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT

That is an off camera flash adaptor.  Not really a hot shoe to PC adaptor but I suppose you could get it to work.  I still think you should try the wireless route.  It really is less difficult.

Thanks I'll try setting things up wirelessly when I get a chance. You may hear back from me if I have a problem though This is all new to me  😉

Once you figure out wireless it's really not that difficult.  Just a matter of getting things set up properly.

If you want eTTL then get the Yongnuo RF-622 ($70 per set), if you're fine in manual only get either the Yongnuo RF-602 ($20 per set) or RF-603 II ($30 per set).  Done.
