I'm received my 6D today and having a blast with it. I also have a 430 EX II that I want to use as a off camera flash. From what I've read so far the options I have ares use a 90EX as the master (trigger) or a Yongnuo YN622C ETTL Wireless Transciever Triggers. I really don't want flash coming off the camera, is there a way to control the 90EX so that it doesn't flash? If there are any other options in those price I'd like to hear from you.
