changing the focal length distorts the picture, or can, at least in the instance im thinking of... but if i build the model small..like a tube or something....theres no real way to fly through it without scaling it up first... or at least thats what i trying to find out...i thought if you could just shrink the camera down to fit the scene or if there was that option... ive just been checking if theres a 'best' way to do it or not...
