Bert Stephani has a nice impressions video on the XF 90mm f/2 →. My favourite part is at 0:29, but keep watching until around the 4 minute mark, where Bert takes the lens outdoors to shoot, and provides some great sample images.
The 90mm f/2 looks like it will have no trouble creating separation for your subject, and rendering busy backgrounds as creamy, blurry, bokeh backdrops. Wedding photographers are going to be all over this thing.
