Definitely much better shots there. They look about as sharp as what I saw from that lens. You might consider slightly higher shutter speeds (e.g., 1/500s or faster) to further reduce the risk of image shake. Don't be afraid to push the ISO beyond 200, as the 16MP sensor is pretty decent up to ISO 1600.
I do also find it unusual that focusing needed MF tweaking; contrast-detection AF is usually very accurate. If it isn't focusing on the right area for you, consider reducing the size of the focus point.
