I have tried to scale a camera before when testing the limits
of POVRay and I couldn't tell that the scale statement did any
more than change the cameras position when the camera was not
at the <0,0,0> coordinates. But, in these tests I never did use 
a non uniform scale, so I don't know yet.

I would hope that the camera could be a "special" object type
that like lightsources, would only pick up the location/orientation
information from the objects they are unioned with. I certainly 
don't think that picking up any normal{} information in the
"lens" would be a good thing.
