Grajan:Looks nice - pity they put the internal flash so close to the lens and no forward diffuser. It looks like it will not be functional at all in the housing making an external strobe a necessity.
I was kinda' worried about the same thing, so I took the camera into a totaly black dark room and found that as long as you are not wide angled out all the way - set at about the 1/2 way mark of the zoom, then if you about about 2 1/2 - 3 ft from the subject, the internal flash seems to light up the entire subject.
I shot this picture of a picture in our classroom with the lights off and the door closed - and it's hard to tell since it is a night shot to begin with... but you kinda' get the idea that the coverage seems to work pretty well.
Of course, there are always advantages to the external strobes - better lighting, less back scatter, interesting shadows for a more 3D look, etc. And they do have two pretty inexpensive strobe options... either about $150, or up to $300... But the shot below is with no externals.
