I've not had any issues with blurriness if I am at the correct shutter speed. There is some barrel distortion at the outer side edges when its wide open. You can see it in geometric shapes like wheels or trees. This is typical of wide-angle lenses tho. I've learned to be aware of it in my composition but when it happens I generally don't crop it out.
With the 10-22mm lens I will crop excessive sky or foreground in some pics.
