Long lenses with larger apertures will never be small DA or D-FA wil be about the same. Because of this they will also have heavy focusing mechanisms (even if the gain some by using IF), and that is were they really need USM. All of the lenses they have introduced recently have light focussing mechanisms that can be drivenby the motor in the camera without any problems. This, together with the fact that som many long lenses have disappeared, make me believe that they are up to something.
