This first brief review is greatly appreciated!
The A7R would be amazing if only it could be massaged into doing raw, a la the Magic Lantern hack (not likely on the Sony).
On the RX10, you mention that stabilization is good, but may require some good contact points at the longest focal lengths. Is there any actual "image stabilization" built into the RX10? (I'd love something like the 5-point stabilization of the Olympus OM-D E-M5 or M1!)
I'd also love to know just how slow the motor-driven zoom is on the RX10, if you could somehow quantify your impressions
