Please note that if you are one of those people who are trying out the Luxpose exporter to Luxrender (or considering it), Luxrender does not understand it if you scale your camera over 100%. I was having a problem with this initially on export.  The scene in Lux would come in super zoomed, not at all what I had for preview before export. Then I was alerted to this scaling thing and checked my main camera. Somewhere along the way with some preset my main camera had been scaled to 264% and this is why Luxrender was giving me a super zoomed in image. So scaling the camera is only a problem if you want to go to Luxrender.
