Yes
If I was to remote mount the 580 and have this fired using the RF-602, could a slave 430 (or another 580) be fired remotely using the 580 as a master?

For my 2nd speedlite I'm looking for a 430 and was wondering if I needed to buy a 2nd RF602 receiver?

Cheers,

Marcus

No. By using the RF-602 you are shooting in manual and disabling the E-TTL system, and all auto-exposure options including remote slave facility. You will need another RF-602 receiver to fire the second flash.

On the other hand, you should be able to use the 580 as master in E-TTL mode and that will fire up to three remote guns with E-TTL slave facility (which most have). You will retain full E-TTL automation.

The only drawback is that you might run out of reliable range if you are shooting outside in bright light. That's the benefit of radio triggering, but if you can retain line of sight between master flash and slaves, they work pretty well most of the time and the E-TTL is a great benefit.
 
I'm foregoing the ETTL by using the guns remotely with the RF-602 system anyway, but was wondering if the master slave facility would work when the guns are all in manual? The camera tells the 580 to fire via the RF602, then the 580 tells its slaves to fire on the set manual setting. What you have said Hoppy is that by going to manual this also disables the ability of the 580 to act as a master?

I don't want to waste the resource of the 580EX being used as a master on the camera with the flash switched off, as that is quite an expensive remote trigger.

Yes, in this situation. It gets horribly complicated. There is full manual-manual, and also E-TTL with manual power settings where the master/slave relationship still works, and only the auto-exposure control is disabled. For any E-TTL operation, the master needs to be directly on-camera, or connected by dedicated cord/s (you can link at least two cords together okay).

More simply, if the RF-602 is introduced then this breaks all E-TTL communication and the master/slave function is completely disabled.
