Donald, Render Blowup WILL do what you want. Try the following: Place the camera in the required spot (your basic back against the wall scenerio) and aim your target PERFECTLY LEVEL. Now increase your FOV until the required portion of the scene is in view. This could take you to a 12-18mm lens but don't worry. Now, use Render Blowup to crop the desired area of the scene – perfectly vertical lines and the fish-eye lens is causing very little distortion at the extremeties. This is essentially how a 4×5 camera "correction" works. Since it is available in the Keyrframe, you are also able to produce a perspectively corrected walkthrough – something impossible with a PC lens. Now if we could only save the settings/crop-points of a Render Blowup for subsequent re-use <g>. Hope that helped a little, – Phil
