Glad I read this thread before upgrading from the alpha300
It actually steared me away from the K3 towards D7200 which is perfect for my purposes:
high ISO (10000 and up) , slow(ish) shutter aided by image stabilisation, high DOF (small appt) and 2nd ctn fill flash...
HOWEVER, the D7200 has been reported to loose shadow-detail below iso 3500 (google /youtube reports, not own experience so far)
at lower iso, the D7100 seems to be the better choice.
I'm not writing this to promote Nikon, just to emphasise the importance of doing some research(and even renting/borowing) before buying
There are no (or verry few) bad camera's/brands, but even within one brand it seems difficult to define which camera suits your specific needs.
Still hoping Pentax will be able to resolve the issue though,
perhaps they could include an option to choose between 'exact but slow ttl' and the 'fast but less reliable' one,
(if they can do it for 'shutter priority' versus 'release priority', why not give users this option too ? )

Meanwhile, best regards and 'happy shooting',
