Of course, fast "film" (i.e. "ISO setting") to go with the fast shutter speed. I hail from the era when anything over ISO 100 film would cost you extra... =:o\ (I usually bought 200, as an almost-adequate compromise for indoor and outdoor shooting.) And presumably the telephoto lens gathers a decent amount more light per radian than the cheaper basic lenses I had.
