TY to those who nudged me towards the 600/st-e3 system. So far I'm really liking it. The controls on the ste-3 arre a little hard to get used to but I'm getting the hang of it. the biggest bonus so far is the ability to do high speed sync off camera - that's been one of my biggest issues lately - yeah I know you can stop down to keep things within the 1/200th limit, but, I'd rather have more control over my depth of field - and I do like shooting wide open (or close to it) - so having the ability to high speed sync off camera is quite awesome!
I forget who mentioned it, but, yeah, I do feel like I need to label my flashes now because it is easy to set them up then wonder which one is A and which one is B and which one is C....lol
