It's been years (like about 20-25) since I used any sort of on camera flash (i.e. -- Sunpak and the old Vivitar 283). I've had a hot-cold relationship with the Canon Speedlite 580EX II lately. Mostly, I've hated it since I've had trouble balancing it for micro-fill (often over flashes, even dialed down, and especially when set to "evaluatieve" metering -- averaging was a bit better). Lately, though, I've found it works well if I use it manually, usually around 1/4 or 1/8 power, and I love the hi-speed sync.
I've usually had an assistant holding the flash with a long coiled syn, but it's sometimes areal pain, especially because I want him closer for quicker recycle, and me a little further with a little longer lens. Then I found Radio Popper, which supposedly is good to 1/1000 sec for hi-speed sync. It seems like a great idea, but at $500 for both transmitter and receiver, quite expensive. Anyone use it? Are thee other similar products out there?
Thanks, Nemo
