Sigma 18-50mm f/3.5-5.6 DC

I just bought it as a 2nd lens in addition to my 28 -135 IS. It was cheap, so I did not expect stellar image quality. But this lens is really nasty, it has an allways unsharp area about 10% from the left hand, oddly its ok reight hand. Maybe de-centered?

This effect does not go by stopping down the lens.

If the image quality (in terms of resolution / sharpness / contrast) would be like on the right hand side, I'll rate it about 6 on that scale above
