This would be a version of the Speedbooster that would pull the entire image circle down to cover the m43 sensor. Similar to what is being done for the APS-C size sensors of the Nex right now. Thus getting the same angle of view from my FF lenses on the m43 body as I would get on a FF body. This would be instead of ending up with a 1.4x multiplier on m43...
So perhaps an FF equivalent angle of view? Or the .5x focal reducer for M43? Pipe dream, I know, and I plan on being fully happy with the .71x version when it becomes available for Nikon to m43.
But that is why I am interested in the potential of the Nikon to Fuji version as well (I'm not a Nex fan ergonomically). Having that adapter would get me to being able to use my nikkors at an equivalent angle of view that I had with them on film.
