D600 still has dirty sensors from the shutter. Go straight for the D610.
If your thinking about the Df, i suggest testing it out for half a day before buying.

Mirrorless mainly use CDAF focusing (contrast detection - slower but more accurate) and now PDAF (dedicated focusing pixels on the sensor). This whilst it is being refined, tends to be slower than the more complex DSLR separate AF sensors but also tends to be more accurate. There is no alignment of a separate AF sensor, need to fine tune focus for various lenses that shifts with different coloured lights or for zooms - different focal lengths.
So to some degree any DSLR is going to have this as a potential AF problem. The latest Sony A6000 shows that mirrorless on sensor PDAF pixelled AF is going to be the way of the future. It is easier to make and because the focus pixel is on the sensor you get rid of that potentially troublesome callibration of a separate AF sensor.
+1 for mirrorless there. Another year or so and DSLRs will be passed on this point of AF speed and accuracy. Although more likely the same technology will be implemented in DSLRs as it is already in a few models.
