Hope you can help.

I've recently acquired an ST-E2 and currently use it with my single 580EXII. I'm looking to expand upon the number of flashes and am looking at the 430EXII's or equivalent to minimise cost. My first question is.

If I were to place a 580EXII left as group A and a 430EXII right as group B, on the basis that the 430 didnt max out would they both give the same output if the ST-E2 was set as 1:1 ratio? And thus give equally balanced output as I adjust the ratio left and right?

Second question. On the basis that I can use different Canon flash units and still get balanced output, what flash units other than the 430EXII and the 580EXII are compatible with the ST-E2 ensuring that I can continue to utilise the E-TTL function.

Thanking you in advance.
 
yes you are right. Other flash units to look at on ebay are the 550EX and the 420EX. Other flash units from Canon cannot be used as slaves.
 
provided you are comfortably within their range them yes, no issues with balancing output. I use a 580 with a 420 both controlled by an ST -E2

I do the same. Use them with an ezybox hotshoe softbox and a reflector on stands.

Yes.

Just for comparison, 430 is almost exactly half the power output of the 580, so if you were working in manual, the 580 on half power would match the 430 on max.

Not just Canon, but almost any brand of new Canon-compatible gun is E-TTL enabled these days for slave mode. However, only a handful of top end guns from third parties will do master flash control.
 
I was advised by a Canon pro trainer to avoid the 420EX as it didn't work too well. His recommended list for ST-E2 was 430EX, 430EXII, 550EX, 580EX, 580EXII

Probabaly because it's 'auto only' gun and has no manual settings.

Definitely something to consider whenn considering a purchase. I want the option of both manual and auto so prob wont look at these.

Exactly what I have, works great in ettl mode, but bear in mind it's limited range with the ST-E2. Great for indoor shots though.

Yup, I have the FITP wireless triggers for manual mode and worked this out after this shot.

Guess which floorwell has the 420 and which has the 580 :D
