That is not exactly true, try finding an f3.5 10mm sample online with that bad corners of this lens... you will find it hard.

No its not hard.
Anyway, just have a look here so you can agree with me and we can settle the op's question: http://hamish1975.wordpress.com/quick-an...-dx-if-ed/
Quote of the operater of the page above: " 10mm wide open pictures are still very unsharp and “blurry†at the extreme corners but quality increases quickly and dramatically as you move towards the center of the frame, where it really is quite good to excellent. Stopping down increases the quality of detail in the corners also, but not really much before f8. In my sample it appears that the top corners suffer most."
