First I need to say that while the PerspectiveCamera is being controlled by the Ab3d.Camera, you should not change the PerspectiveCamera directly. Because the PerspectiveCamera does not have a Changed event, the Ab3d.Camera is not aware of the change.

I really need the combination of both a first person movement (pan) and a Scene Camera together. I am trying to inspect objects in 3D (scenecamera style) then be able to move from object to object (firstpersoncamera style).

This request lead to redesigning the cameras for the release candidate.
Now you also have the MoveLeft, MoveUp, etc. methods available on TargetPositionCamera.

This way you can use the TargetPositionCamera for inspecting each 3D object (just set the TargetPosition property to center of the 3D object's Bounds) or for inspecting the whole scene (set the TargetPosition property to center of the 3D Bounds of the root Model3DGroup or Visual3D).

You can also animate the TargetPosition from one object to another with WPF's Point3DAnimation.

When you have set the TargetPosition you can rotate the camera around the object with changing Heading and Attitude (or by MouseCameraController or CameraControlPanel). You can also strafe the camera left and right by calling MoveLeft or MoveRight methods. You can also use MoveUp, MoveDown, MoveBackward and MoveForeward.

I hope this will suite your needs.
