I have a quick read at some internet review of the particular camera and see some of the test shot. Actually it seemed to be there have been some corners that are not as sharp as the center of the lens. So I think it is more or less there. But if in doubt... CSC is always your best friend to go to.
Actually not bad already. Distortion is almost not there. You should have seen some of the sample shots I have seen in the net. This is consider not bad at all. But as I say, if you find it still suspicious and annoying, maybe give CSC a call or visit and see what they have to say.
Suggest TS to not worry about it. You pay for what you get. And yes, even more expensive PNS will be likely to have the same problem too. Heck, a bad lens on an expensive SLR will also give you similar results.
