I agree, this camera is the real deal. It has a lot going for it. The size is delightful. For example, with the 75/1.8 Olympus lens, it is a tiny little thing compared to a DSLR with a 70-200/2.8, 70-200/4, 135/2, 200/2 or 200/2.8.
The autofocus is excellent for portraits and most subjects. However, so far I haven't had very good luck with indoor sport (basketball) in a poorly lit setting (ISO 6400, 1/500th, f/1.8). At such a low light level, the autofocus doesn't seem to work as well as the AF on my Canon cameras. I've been trying different settings, but haven't yet found one that is really satisfactory for that.
