A real challenge for photography is using your equipment after dusk. And even my trusty X Pro 1 will stand this battle without a flaw. I mainly used the 18mm and the 27mm to capture some photos in the beautiful historic city of Luebeck. There where a lot of Xmas fairs going on. The most shots were taken with an aperture of 2-2.8 to get higher shutter speeds to capture movings things with a little motion blur.
