Shot with and X-E1 and 580EXII flash and shoot-thru umbrella to even out the light, one of my favorite bags the Billingham Hadley Pro.
I've had my Hadley Pro in sage for just under a week now and love it (had the X-E1 for just 2 weeks, love that as well). Used them both properly for the first time yesterday and they are the best camera and bag I've ever bought.
One question: What method do you use to fire the Speedlight off the X-E1? I've an 550EX which I plan to keep when I sell my EOS gear and haven't yet thought about the best way to control it from the Fuji. Might also invest in a compact umbrella now.
