I would photograph a planar surface with the lens wide open, something like 
our favorite brick wall. I suspect this is a camera issue and maybe not 
operator error,or maybe it is. I think either your lens is not parallel to 
the back or there is a problem with the film back. If one side of the 
negative is soft, can you swing the camera to get it in focus? Are the 
detents (does the camera have detents?) causing the camera to be out of 
alignment when you first set it up?
