Im wanting to get a strobist kit setup. I understand the 580 ex works as a master and the 430 ex works as a slave. so with that in mind i only need one receiver going to the 580 ex flash right?
My other question is, if the 430 works as a slave, then is there a radio unit that will send out a signal that will just fire off the 430 ex without needing a receiver underneath it... That would be really awesome.
Any help would be great thanks :)

| I have to be honest and say I don't really understand your question. However you need to understand the the 580EX version I will fire the 430EX but the 580 must be on the camera to do so. Can you please try to explain again what it is you are trying to do? If you want to fire either flash off camera you need something on board the camera to fire it. Or you have to use third party transmitter and receiver to fire them and use the flashes in manual mode. |

Like Matt I don't understand your first question. Regarding your second question, you can use an ST-E2 instead of the 580 to trigger a 430. Every other solution I'm aware of requires a receiver unit to be connected to the 430.

Ah, the joys of triggering off-camera flashes.
In 580/430 master/slave operation, one flash (on the camera) can fire another flash (off camera). I believe that in this configuration the flashes retain their TTL auto exposure features. There are no radio transmitters/receivers involved, but the flashes must be relatively close together (aka line of sight). I haven't used this setup.
Flashes can also be triggered via an optical slave - there is no TTL operation or any communication between the flashes. The optical slave flash simply sees the pulse from another flash (any other flash) and itself fires. Some flashes have built-in optical slaves. Again, no radio tx/rx, but they need to be near eachother for this to work. This is my favorite triggering mechanism in studio as it is very reliable.
There are cheap radio triggers that simply fire flashes (no TTL operation - all power settings must be done manually). The radio transmitter sits on the camera, and each flash must have a radio receiver. I've used these and they work marginally well - sometimes misfiring and sometimes reducing your effective max sync speed.
Finally, there are expensive radio triggers (RadioPoppers and I think the latest version of PocketWizards) that work the same way as the cheap radio transmitters (transmitter and sometimes a flash* on the camera, receiver at each flash), but they maintain the TTL operation which means the flash exposure is calculated and set by the camera. I've never used one of these systems.
Describe your setup and desired results and we'll help you get it working.

Basically all I want to use is two flashes, maybe three at the most. I already have a 430 EX II and was thinking of getting the 580 EX.
Basically want I want is something easily portable and inexpensive. I would be using the setup for model and family shoots in the field. My only concern is about the amount of light and if its going to be powerful enough.
I dont want to have an on camera flash.
I will ask around about the radio poppers as they seem to be expensive but reliable. I dont want to lose sync speed and I would like to have a decent range.

Unless you get a 7D (which finally has some of the Nikon like flash functions) AND want eTTL then you need a flash or an STE2 on the camera. A 430 cannot be the master but a 550 or either of the 580's can.
RadioPoppers will need either on the camera as well. |

I will probably just get a 580 down the road and get a radio popper with two receivers. That seems about the right setup for me. As long as its reliable and Im able to shoot in any kind of light them im cool. But for now, im just going to get a radio popper with one receiver so i can use my 430 off camera.

Get some Yongnou 602 transmitters/receivers. Some cheap Youngnou flashes 460II and your set for WAAAAY less than the canon flashes but you will be working in manual.
I would suggest reading strobist.com and the flickr site associated with it.
Good luck

Read carefully about the RadioPoppers setup - like robs said you'll probably still need a flash on the camera. |

| I inquired about something similar this weekend when I got my 580EXII. They were out of the transmitters, so didn't get a second flash, but they also mentioned that there is not remote that will work with the 40D. Is this true? |
