Don't know if this is the same in later versions. In P6 Perspective is not the same as focal. The focal dial does what it says on the box, changes the focal length, and does not alter the POV. Perspective changes both the focal length, and the scale of the camera. I suspect that Perspective will change the POV for the Main and Aux camera (though probably not  the Dolly Camera), but have not done the tests to prove that theory.

I know that the manual says Perspective, will not change the POV, but I never trust the manual to give accurate or useful information. Perhaps it is correct, but I'll need proof before I believe it.
