I just bought a Fuji XE2 with a 18-55 XF lens.  I have always love my Fuji X100 but wanted the scope to change lens. I had a business trip to Liverpool and took the Fuji to see how will it performed.  The Fuji handle low light very well, with shoots taken at ISO 1250 handheld at low shutter speeds coming out sharp and very useable noise wise.

ISO 1250, f4.5, 1/4 S

Water front, Liverpool.  The last bit to be redeveloped.
