Camera settings: I usually shoot in aperture mode and sunny WB when I'm out.
For this camera I set it up as follows: A mode,Auto WB and ISO to Auto 3200.
I was changing the aperture on the lens and just left the camera to figure everything out. I didn't have to worry about ISO settings because these Fujifilm cameras are so good at higher ISO values that you just can't see any noise up to 3200. If the auto WB wasn't any good, well I still have the raw files to play with once the camera is supported. I needn't have worried because auto WB is spot on, and that is indoors as well as outside. Fujifilm have made some advances in this area and have become my cameras to beat for future camera purchases.
Saying that, these cameras might just become my system in the future, once I see what the lens development is like. That 55-200 certainly sounds good at the moment for the X-E1. It's the one area that's missing at the moment.
