56aHi Joc3a3o   not 100% sure which flash mode you're asking about, but I amsuse it's one of the Yongnuo's. The 460 and 462 and 465 do not have zoom but fixed 35mm coverage. They are specified as GN 33 (meters). So it must be GN33 at 35mm for these. YN-467 and YN-468 have the same GN spec so it must be at 35 mm too for these 2   also backed up by light meter tests where they are all the same or very close together. But let me know which flash you're asking about!
