I've owned the M9, the Nex 7, and now the Fuji Xpro1. For me, this quirky little camera (xp1), wins. The nex 7, although a nice little camera, I could not get use to the EVF or the annoying video button. I used a novoflex adapter for Nikon, and Zeiss lenses, but stop down metering, always slowed things up. Another thing was the hot shoe adapter. I simply hate having another electrical connection to think about when using wireless strobes. Make sure you have additional batteries for that too. The menus were quite annoying too, with submenus and explanations popping up every time I used them. Perhaps, with the AF Zeiss, It would have left a better impression. My M9's shutter sound leaves much to be desired in comparison to the silky feel of the Xpro1. With the choice of OVF, video, and AF, and probably one of the best Fuji lenses ever (35mm f1.4), this camera is my choice. There all really good cameras, but for me the Xpro 1 is the better one.
