I was wondering.. The new Canon 600ex-rt flash. Will the wireless radio signal works if I am shooting w/ the Canon 5D Mark II (in ETTL and in Manual Mode) most test I am reading is with the Mark III. I'm sure I read it and didnt even noticed.
I am somewhat interested upgrading to the Canon 600EX-RT by replacing the some of the flashes i have (like the 430EXII/580XII and the RadioPopper PX system). if i get will be getting two 600EX-RT flash
right now if i am to replace the flashes, i dont think i will be able to afford to buy the Mark III camera. that's why i like to know if the 600 flash can do the same stuff on the Mark II camera.
