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

You've been busy. Ok, easiest question first:

$71 for the cable? Hah! Send it back!!! No question about it. That's a set of 622s right there, which can do everything that cable can, and more.

Yes, that information that you saw on Flash Havoc is exactly what I was referring to in my post above. What it means is that you cannot control flash power of the 580ex (original) through the camera menu. For your other flashes you can actually go into your camera's flash menu and adjust power remotely with the YN-622. However, that new transmitter allows you to do it on the transmitter instead of scrolling through menus - much, much easier. Most likely you won't be able to do that for the 580ex (original) but it should still fire fine. I'm guessing that it should even work in eTTL, but I'm guessing. If I'm correct then there won't be any difference with your flashes when in eTTL mode. In manual mode you could remotely adjust the power of your 580ex II and 568 II, but not the 580 ex (original).

As to what to do now, well that's up to you. If this is all too overwhelming for you then perhaps step back, do some research and hold off until you feel comfortable. My recommendation hasn't changed. The 622s are the way to go if you want eTTL (if you want manual only you could go even cheaper).

That link you posted from eBay is good. Too good actually. Yongnuo has an eBay account, that's where they started actually, and their prices are higher than that. The seller has a good rep, but buy at your own risk. Personally, I'd rather pay $10 more and get it from Amazon (with 2 day delivery if you're a prime member).

I found a combo with the LED master for the same price as the 622s:

And then you just get a set of 622s, also for $80:

3 eTTL off-camera flashes with remote power control for $160. Wouldn't even be a down payment for a single Canon 600ex-RT.

FYI: This is the manual for the 622 I was referring to. Don't bother with the one that comes with the camera.

It says that it's eTTL compatible with the original 580ex. So that means, so long as you're in eTTL, you won't see any difference between the 580ex and 580exII. In manual mode you're have to manually change power on the 580ex, where as the 580exII and 568 II can be changed via the YN-622C

Thanks so much! That'll REALLY help once I get the 622s. I cancelled the 10m cord that was $71 (they hadn't sent it out yet). But what I think I'll do is just get a 10m coiled one for $23.49 and keep it as a backup in case I ever need it if the 622s get finicky. I also found a cheap pair of umbrellas I'm thinking I'll get too, just to start out with. I found a pair for $48 with translucent, gold and silver umbrellas, so that would give me 6 total to work with (links below). I'm making my way through the Strobist site, a DVD on the Canon speedlights, and the Speedlighter's Handbook now... It's hard for me to concentrate on just one thing at a time, but I'm learning a lot from each (and from you too!).

The Yongnuo 622-TX sounds like it would be better than the older transmitter. What I'm thinking about doing at this point is sending back the 10 meter cable and getting this: http://www.ebay.com/itm/Yongnuo-YN-622C-TX-Wireless-Flash-Transmitter-2PC-YN-622C-Trigger-for-Canon-... and having them add on one more 622C receiver, that way I could use all three speedlights (I hope anyway). Any thoughts about that?

What I'm thinking about doing now is getting this plus one more receiver: http://www.ebay.com/itm/Yongnuo-YN-622C-TX-Wireless-Flash-Transmitter-2PC-YN-622C-Trigger-for-Canon-... and sending back the 10 meter cable I got. Considering the price of the cable ($71!!), getting the Yongnuo transmitter and receivers wouldn't really be that much more, plus I wouldn't have the cable to contend with.

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