Re: canon 55-250 IS blur edge, anyone?

HI here are the test with vertical shot, one on clockwise (left side on top) and the other one anti clock wise(right side on top). The difference is amazing! anyone experience that? I have tried with the sigma as well and it does show similiar result as the canon on this shot, but the other shots are not obvious. I think it could be my camera(350D) but I think the canon lens has some blur on the right edge as well(in my other test shot, the bottom is slightly blurer than the other side). Again its a weird way of holding a camera.

full shot 250mm f8 1/250s

center area sharpness is the same.
