Camera control is definitely an issue in this game, and it's suspiciously similar to the camera issues that FF11 had, and still does have. The camera seems to have some sort of extreme phobia of getting too close to the terrain or structures in general, and frantically tries to get away from it, making it get very shaky very easily.

I think the camera just needs to be allowed to be positioned "inside" things and allow objects to come in between the camera and the player character, and then instead make objects and terrain that obstructs the view partially transparent while the camera is close to it.
