Thanks for the review. I agree that Sony could squeeze more out of the hardware. I would even presume, that it would have been possible to get 4K from the hardware and also 10 Bit uncompressed HDMI should have been possible, so it seems more a marketing based decision in order to protect sales of their dedicated video cameras.
But I disagree that there is no significant progress compared to a NEX-7. In fact the footage from my A7R is definitely sharper than from my NEX-7 and especially in low light situations you get a much better picture (less noise and far better colour preservation).
Do you have proof, that even though the HDMI output is 4:2:2 the data coming from the sensor are already crippled to 4:2:0?
Do you know any affordable HDMI reorder capable of recording 1080p60?
Best regards
