Hi Forest, The Camera simply doesn't have a "zoom" scale, it just has a view matrix.
The "zoom" is only relevant to specific camera manipulator models that have a concept of zooming - like osgGA::TrackballManipulator and osgGA/TerrainManipulator, so you could get this info directly from these if you are using them.
