Don`t worry I won`t pretend to be a camera tester. But one of the things which bothered me in real life use with ilc, including Fuji XE1 and OMd (which I used shortly), was the inaccurate and sometimes unpredictable AF. AF speed is another matter. THe GX 7 which I picked up has a very reliable and accurate AF. The best I have experienced so far. Speed wise, I believe it`s even a tiny bit faster than the OMD. Plenty fast. Attached shots I tried several times, with changing focus from one to the other handle. The GX7 always got it right, fast and no hunting. In camera jpeg, iso 1000, NR turned off, f2.8, Sigma 60mm (a great lens, not only for its price).
