I have better understanding on flashes after marathon-watching the videos in YouTube and I think the off-camera flash is really interesting which I want to do it. Went window shopping during lunch time to check on the prices.....if I am going to get the 580Ex, I can top up a little to get the 600EX-RT (Gray Set)....Hmmm.
OK I know people is going to shoot me for this noobie question...If I am going to pair my 60D with the 600ex-RT, am I suppose to get a transmitter for my body to trigger the 600ex-RT? Or it requires 2 gadgets on both body and speedlite? Thinking of the off-camera flash, I will prefer to do it wirelessly...
you don't need trigger.
you can use the built in flash in 60D body to trigger Speedlite.
As long as they are in one line of sight, no barrier, they will communicate.
search YouTube (I think it has in one of my link I gave you) / Google to find out how to activate in 60D body and in Speedlite
