I've been wanting a flash, but was kind of waiting until I could afford the big one.


Some of the trigger systems depend on a camera-mounted flash, but not the old PWs and not the new PW system (in basic mode). To have the camera perform E-TTL operation with multiple flash groups, you'll (temporarily) need an on-camera (aka on PW on camera) 580 to manipulate multiple zones. Unfortunately the in-camera zone controls on newer cameras is not available to the PW system. PW is developing a "Zone Controller" which provides a direct control for three zones of light (most likely within the confines of Canon's zone system, namely that the C group is intended as a background group and should not be illuminating the subject). I for one can't wait for this option.


As someone else already pointed out, there are some legitimate reasons to get the 580. If you need the power, you need the power and there's no substitute (well, two PWs and two 430s...). Last winter, I took some pictures of our indoor Christmas village, and used Rosco 58 gel to create a moonlit look. With a 580 on a stand 4' above the village, I didn't have enough power, and had to fly a second flash to get the shot. I also happen to be addicted to the option for the external battery pack.
