Has anyone experienced A/B ratio problems with the ST-E2 flash transmitter on a 5D2 ?

Seems like mine does not change power between a-b ratio, maybe its just me though ? I am using 2 580EX II . Thanks

Heath

I'm using it with a 550EX and a 580EX and haven't noticed a problem.

I've used the ST-E2 with 430EX, 420EX and 5DII and it worked great. Clean contacts? Line of sight? Slave mode set on 580EX?

Hmmm.. I will give it a try again, maybe the batt is low ? One strobe set to slave A , another set to slave B, right?

Thanks

No problem here too.

Are you new to Canon flash?

If you put the 580exII flashes in slave mode on the same channel as the ST-E2, with one in Group A and the other in Group B, it should follow the lead of the ST-E2 master.

You might also try using one of the 580exII as Master and the other as slave. That's how I use mine. It provides needed fill and overcomes the inherent range problems of the ST-E2. See this tutorial for step-by-step instructions:

Note if using the 580exII as Master it defaults to Group A and the Slave must be set to Group B via the zoom button.

Thanks Chuck,
Ive used this set up on my 1DMarkIII many times with better results.

Works well here too.

Try a new battery in the ST-E2
