It's f/5.6 at 11mm. Looks like a little field curvature and distortion. To be expected with a lens like this.
At f/8- f/11 with proper focusing I would expect that scene to be edge to edge sharp but still have distortion (to be corrected in camera or in post)
Focusing at hyperfocal with lenses that have field curvature is asking for weak edges.
Have to focus further into the scene. Or focus at the edges (manual focus with punch zoom) then check the center is still sharp, if not adjust to get even sharpness across the frame.
