Same sensor as the X-E2 and X100S but with an improved EVF and faster operating speeds with a claimed worlds fastest AF speed (for this camera type)
Got to hand it to Fuji, in the last few years they have produced an entire system of cameras and lenses that are top quality.
"DPReview's Andy Westlake expressed his disappointment that there's no option to directly move the AF point using the four-way controller, as is possible with cameras like the Nikon D7100 and Olympus OM-D E-M1. Instead you're always required to press the 'down' arrow first, to enter AF point selection mode - a small point, but something that's fairly unusual at this level."
