Therefore, a 2x on an f/1.4 lens, e.g. the 80/1.4, will turn out to be a 160/4 lens. The 1.4 f/stop isn't usable so you cannot get a 160/2.8 out of it. Just f/2 which = f/4 with extender. In addition, anywhere the APO 2x extender can be used, so can the non APO 2x extender. Only with, perhaps, less resolution in the result.
