So having recently moved to my Canon EOS 1D Mark III i have realised i need a wireless flash trigger. I want to have my Speedlight 430EXII in an umbrella off camera and don't want to use sync leads. Can anyone make any recomendations for this? Do i need 2 'things' one for the flash and one for the camera or can i just pop one on top of the camera and use the flash to recieve the signal?
i think i'll see what money is left over after payday!
