The Zoom H4n windscreen works great on my XF-100
 

Although it does block the volume control and one of the XLR connections the foam windscreen from a Zoom H4n works beautifully to null the wind sound which can be expected without it. I've been shooting in the marshes of Southern Oregon during high winds and the audio is perfectly usable. In a pinch this is good to know.
Also, after shooting HDSLR video over the last year I've gathered more peripherals than I want to deal with BUT I've found some of the gear translates perfectly to use with the XF-100. For what it's worth here's a picture of my XF100 sporting a few of these items.
