You're wrong
All Nikon lenses control their aperture via a small lever at the base of the lens. The MFT / Nikon Speedbooster has an aperture ring that moves that lever in 1/2 stop increments, giving you full control over the aperture manually.
This is why I always by Nikon lenses or Nikon versions of lenses - that little lever means that with a cheap adapter, you can get manual aperture control on any camera.
