Corded flash set up

Canon made TTL Hot Shoe Adapter 3 which sits on top of your camera. It is connected to TTL Distributor which can split up the connection up to 3 flash. Each flash must be equipped with Off-Camera Shoe Adapter OA2 for the cable connection with the TTL Distributor. It is not going to be cheap, but it will work for sure. I'm not sure about the range limitation (cable length) though. Hope it helps.

Lookout, a corded system based in 8 standard PC connections? Sounds like intermittent flash hell to me.

One at the flash
One from the camera flash cord to the triple PC splitter.
One each from the PC splitter to each of the three flashes (three total)
One each at each hotshoe to PC adapters (three total)
---------------
Add them all up - Eight Total

I would not touch that setup with a whip, a gun, and a chair.

Interesting!

What would you recommend using in a sync cord setup with 2-3 flashes?? in terms of splitters, adaptors, no. of flashes, etc.

Would it help if you didn't have to use hotshoe to PC adaptors? (like using Nikon flashes which have a PC terminal already)

At the moment i'm using just a sync cord and 580exII, but would like to add another flash like a SB-28 or something.. or sell the 580 and buy 3

But your 40D, your 580EX II, and the Nikon SB units you cite can accommodate the Screwlock PC connector (in addition to the standard male PC connector).

The Screwlock PC connector does not have the reliability issues of the standard PC connector. But, it does take a bit more time to screw the locking collar in place.

In general, for multi flash corded setups, I would recommend leaning on the mono miniphone plug gear for splitters, extensions, etc. And using short adapters with the needed connector at the flash.

The mono miniphone gear is inexpensive, compact, reasonably available, easy to set up, and very reliable.
