Carsten, Yes for both.
Seattleducks, Your experience with this lens is typical. As you see in the photos, the curvature becomes quite flat at 28 to 35mm. It also coincides with the zoom physically reversing the movement of its elements which might mean that these 2 settings could be just "optical magnification" of the 24mm setting, which might explain the flatter curvature. As I mentioned earlier, it does help a bit to slightly front focus with the lens for better corners.
