I have a 7Dand also a 600EX-RT. I am wanting to know that if I buy another 600EX Flash will it work with the radio transmitter on the 7D instead of buying a ST-E3-RT and then another flash later? I am looking for advice and/or suggestions. Thanks
Awesome. Thanks for the quick response. I am easy about using the flash for set up if it cant be done on camera because that will change when they go on a 5D MkIII.
