Hello there POTN community. I have a question regarding off camera flash.


I am wondering what would happen in this scenario:

- I have a Canon 5D MKII attached to a Canon ST-E2 transmitter.
- I have a 580EXII flash placed on the LEFT on a stand with an umbrella attached in front.
- I have a 430EXII flash placed on the RIGHT on a stand with an umbrella attached in front.

Since I am using the ST-E2, I should be able to use TTL on the two flashes, but how would I do so since the umbrellas might be blocking the TTL. How is it going to measure the distance? Would I need to use full manual mode on the flashes? Is there another way to carry on this setup?

Thank you very much for your help and time!

It should work fine.. TTL = through the lens.. which is how the camera evaluates the exposure.. In this case it will evaluate ambient, as well as the pre-flash coming through the umbrella.

That being said, just make sure you know why you want to rely on ETTL in this situation, rather than just not knowing how to do everything manually.

Twist the 430EX and 580EX so the remote sensor faces the ST-E2 master.

Even if there's not direct line of sight between the ST-E2 and the slaves, it usually does pretty good indoors... the master control signal reflects off of interior surfaces.

Also, if this is hypothethical (e.g., you're still shopping and don't actually have all 3 components to test it yourself), I'd recommend the Yungnuo ST-E2 over the OEM Canon ST-E2. Not only is it less expensive, but it takes AA batteries and has much better signal strength and angular coverage.

Ahh.. I misunderstood. He's not talking about the evaluation being blocked, but the communication between master/slaves. Rotating the head/body makes perfect sense to me. Good call!

Well I was just wondering if the 580EXII and the 430EXII would properly expose my subject based on the TTL information. :D I was a little curious of how that would work out :rolleyes:

I was looking at the Yongnuo ST-E2 and it had mixed reviews. Time to do more reading!
