ISO 160 - This is "Max" (slowest & highest quality ISO) for this camera. Very good image quality but is it just because these are sample shots or why didn't the photographer elect a smaller (more narrow) aperture for greater DOF. Obviously movement within the scene is not a major factor. I'm sure 1/125 would have "frozen" any slight movements in this scene.
I do wish camera specs included the maximum "stop-down" apertures as well as the maximum "wide-open" apertures. I would surmise a camera of the quality could be stopped down to f/22 but then I am only speculating.....?
