Just got done shooting the first day of a doc on the F3 and I've got a couple of observations. First, I LOVE LOVE LOVE this camera. I wound up shooting at a 0 gain (800 ISO) with only a chimera'd 650W fresnel for a key, a 150w pepper hair light, and a bounce card and I was still a smidge over exposed for my tastes. Second, You absolutely need the best calibrated monitor you can get your hands on because the lcd's are really tough on old eyes. Finally, and this is cool, you can program the firewire output to SD and use it with OnLocation for a SD feed/record.
