Can I use the 430 EX-II as a slave with a 5D?

I need to do this for my new photography job. I don't have a 580 for a master, or an RF-602 wireless transmitter or anything, just the 430 EX-II and 5D. Will this work? If so, how? I can't find any topics on the web that answer this. Thanks!

No, you need a 7D, 60D, 580/550EX or an ST-E2 to use as a master for Canon's wireless system.

no, not without an additional trigger device, or an off camera cord. Only the 7D and 6OD have built in wireless triggers.

So, what could I get that is cheapest and would work? This?

The cheapest that wlll give you full ETTL control would be a long off camera cable from www.flashzebra.com. If you are willing to accept manual flash, the RF602's are a reliable option. You might also look for an st-e2 transmitter, to master the canon flash. Other options are more expensive.

Yes, I would be using manual flash since I am doing portrait photography. What are the basics I should know to slave the 430 using RF602s? For example, how would exposure figure into the added fill, and what settings do I use on the 430 to slave it manually? Thanks for any help, I have my first shoot on Wednesday and would have to order to 602s today... just busy until then.

THANKS!

You set the 430exII to manual mode (not in slave mode) and attach it to the RF602 receiver. Set your shutter speed below max sync on your camera, 200 or less. In M mode your flash is capable of full, 1/2, 1/4, 1/8, 1/16 etc power. You might want to start out at less than full power, that way you have the ability to adjust upward or downward as needed. Take a shot at your preferred aperture and take a look at the histogram. If you need more or less power you can either adjust the light or adjust the aperture (or ISO). Adjusting the flash power will not affect the ambient light, but changing the aperture or ISO will. Keep in mind that you are actually calculating two different exposure values in this process. One for the ambient, and one for the flash. Changing the shutter speed is the easiest tool for adjusting the ambient (area not affected by flash). Shutter speed doesnt really affect flash power as all the flash is delivered in a short burst anyway.
