http://cameralabs.com/reviews/Fujifilm_X-T1/ I like Gordon's reviews - always fair and balanced. Good discussion comparing XT1 with Oly EM1 and Sony A7. Regarding the XT1's C-AF abilities: - X-T1 is the only mirrorless camera with a decent sized sensor that can actually keep a subject in motion in sharp focus even at 8fps with a very high success rate. The only other one is the Nikon 1, but its 1 inch type sensor is considerably smaller than the APS-C sensor in the X-T1 - Using the 18-55mm f2.8-4 zoom at 55mm f4, I photographed bursts of marathon runners approaching a finishing line, along with my own kids legging-it towards me across a distance of about 50m. I also repeated the tests under a variety of conditions. In all cases the X-T1 delivered at least an 80% success rate, and in many cases higher still. Indeed on some occasions all of my shots in a continuous burst were in sharp focus, and all when using the camera's top shooting speed of 8fps too. - The Single AF may not be quite as quick as the latest Olympus and Panasonic models, but it's at least as fast or faster than other rival cameras. The Continuous AF meanwhile is the best I've used on any mirrorless camera with a decent sized sensor, finally allowing us to confidently track a subject approaching or receding at reasonable speed. - X-T1 is far more successful at continuous AF and tracking action [than EM1] - Both [the A7 and X-T1] may have embedded phase detect AF points on their sensors, but the X-T1 is far more successful at continuous AF and tracking action. - Overall the focusing on the X-T1 is a triumph. Fuji, you've come a long way baby!!
