No4 is a corker, nice one
I had an experia (X1) and didn't rate the camera too much when the conditions were a bit dark, but your pic's came out great, especially 4 and 5.
The aerial shots should be interesting, do you have any experience of this? Saw something on telly about it a while back, and recently I think someone even got curvature of the earth shots, quite amazing really.
