Hi, I hope this is in the correct forum. I'm a happy owner of Olympus OM-D. I'm coming from the Canon DSLR world so I'm still getting used to things. I've got a FL600R flash that I wanted to use with my Olympus OM-D. Mainly off camera for portrait and macro work. Whenever I use the clip on flash to trigger the FL600R it acts as a fill in flash as well. Which I don't want it to be. This happens when my lens is wide open (f/1.7 - 3.5). Is there a way to avoid this? Will the pop up flash always interfear with my main flash? I used to have a Canon 580EX with a transmitter so I didn't have a problem with this before. This is a big problem especially when I'm doing macro work. Is the only alternative a remote trigger like pocket wizard? Thanks for your help!
