How is variable zoom done?

[Stublerone]

I wanted to get used to 6dof now, but as I already did in 1946: Just switched it back to x and y and performed akdditional important movement with axes or a hat.

Did you also encounter, that the amera is not shaking so much in the good old mode with just 2 or 3 axes. I just heard something about that, too.

But nevertheless the should only go back to old style switching between the modes without limitations in angle anf with zoom factors not affected, when switching modes.

Looking forward to your answers.
