Just what I needed

Perfect fit for my 645 Pro, and my RRS ball head.
Also Fits Phase One XF

I Bought This QR Plate For The Mamiya RZ67, But I Just Noticed It Also Fits The Phase One XF Camera. If You Need A QR Plate (and Not An L-bracket) For The Phase One, The Acratech 2150 Works Great, At A Fraction Of The Phase One Price.
