RX1 going back

and don't get a OMD either, expecting miracles with moving subjects.

Even a lowly PDAF DSLR will be better for toddlers. I know, I speak from experience, having had both the OMD and the RX1. However, I never got either of these two for primarily photographing my son (though I'm able to get keepers most of the time), as I'm using my D800 or A99 for those challenging shots. I actually don't care much for the A99, as it's AF, though capable and decent at tracking, is severely limited to the central 1/3 of the sensor. The only reason I got the A99 were the yummy CZ lenses (135 and 24-70).
