Question about Canon EOS 40D Digital Camera
I am trying to fire some remote flash units with my 40D however I cant fire them with the main camera flash or my Speedlight off..? Is it possible in settings to manage this on the camera..or do I need to use the remote cable that is supplied with the flash units..? Hope this makes sense...thanks Paul
The EOS 40D does not have a transmitter built in. The remote flash units must be set to "Slave" and the on-camera external flash unit (eg Speedlite 580EX) or transmitter (ST-E2) set to "Master". Note that the Speedlite 430EX doesn't have the function to act as Master and you need a minimum or the 580EX or a ST-E2 speedlite transmitter (or similar) as Master/s.
