If it is a transform than you can just use
camera{
location -z look_at vtransform(<0,0,0>,Gregs_camera_transform)
}

I have no idea what your transformation is exactly but it can be important that
(what I see in sources) transformation is not applied to focal_blur parameters.
Perhaps transformation should be also added to normal of camera.
