| Quick question for those that own this product. Can this flash be used off the camera. If I sit it to the side of someone and then set up my camera away from it will it automatically go off when I take the picture or does it have to be attached to the camera?? Thank you |

| You can fire it remotely, but you need a wireless trigger, about $200. |

If you have a Canon ST-E2 or a Canon 550EX or Canon 580EX, they can all serve as "masters" while your Canon 430EX functions as a slave.
Alternatively, just get a long cord and run it from the camera to the flash.

So, do you have to always have a flash on the camera? Or does the Sigma flash as shown below allow you to not have it on the camera?
Sigma EF-500 DG Super E-TTL II Digital Flash
I just wanted a flash that could be placed on a bench for side lighting or on the camera, whichever I want at the time. Can this not be done except for purchasing more equipment? Thanks

| Well.. yes and no. Depends on how you define equipment. You can do it with any flash by taking the flash and adding a PC sync adapter to it, and then adding a hot shoe to pc sync adapter to your rebel, and connect them with a long cable. So with two adapters and a cable you could do it. |

Well the Sigma flash can be used as an optical slave. This means that the flash will go off when it "sees" another flash fire. You could, and this is what I do, set the flash off to the side and fire it with the onboard flash. The only things to consider is that doing this means that you have to have it in full manual mode and you also have to consider the impact of the onboard flash firing as well or figure out a way to block it out. The Sigma can act as a wireless master as well, so you can use it to trigger other flash units wirelessly and also use full auto exposure (ETTL2).

Hate to drag up yesterdays news, but I have a question about this flash and didn't want to create a new post. Is the canon 430ex capable of operating as an optical slave?
Edit to add:
I did some digging and found that the Canon 430ex will NOT work as an optical slave. It needs another flash that can send a signal to it to tell it to fire. Just in case someone is reading this down the line from me with the same question.

What do you mean by 'optical' slave? The 430ex can operate as the only flash or as a slave in a multiple flash setup. It cannot be the master.

| By optical slave, I mean firing when it senses another flash fire just by "seeing" the flash with its sensor. The 430ex can't do this. It needs a specific signal to tell it to fire from a master flash or from the wireless transmitter (ST-E2). I was wanting to use my flip up flash to trigger the 430ex, but it can't. It has to be from another flash capable of sending out the signal, like the Sigma EF500DG Super or the 580EX. |

Right, but the 430EX (while on the camera) can trigger the Sigma 500 Super with an optical slave since it has one built into the flash. Works great, I use it all the time.

| That's correct, the Sigma is capable of operating as an optical slave. The 430ex is not. |

I use a simple hotshoe adapter to trigger the 430EX as an optical slave, it cost about $19. You can also get a fancy version that will prevent the pre-flash, from canon's E-TTL, from triggering you flash. I use mine in manual, so the $19 worked just fine.
As previously in this thread, a 580EX, ST-E2, pocketwizard, or plain old sync cord will also work. The 430EX is a very nice little flash with a 5stop range of manual adjustment.
