Well if this is out of the camera (ie. you haven't played around with it except format) them I'm impressed. Colour is excellent - the shadows have a slight blue cast, true, but I would have expected more in the conditions.
The building in the background is probably more revealing than the main subject - very clean, excellent resolution and no nasties ... except I can detect a VERY faint moire pattern on side of the building (or perhaps its my monitor
. I can't see this being an issue, and I'm not sure other cameras would have avoided it (maybe the Sigma).
Nose of the aircraft looks a little soft - suspect that's an operator issue though
Yeah, go on, shows us some high ISO ... but its looking good so far!
