You have effectively used 4 different lenses in your case, and consequently 4 sets of lens parameters need to be evaluated by the optimizer.

When you can't assign many control points, it's best to use calibrated lens parameters that have been evaluated in a special project shot in a carefully chosen venue that facilitates the assignment of control points.
