Between the A77 and A77ii, I haven't had nearly enough time with either to give a proper evaluation to. And like MedMan, I only use one lens with it (just my 200 2.8 prime).
But here are a few thoughts:
--The used A77 I picked up from Adorama for $351 shipped was an absolute steal and I feel like a gear whore for not sticking with it. The images and frame rate put my old 60D to shame
--That said, the A77ii has even better IQ, buffer, focus acquisition and tracking.
--The A77ii is like having an A6000 in a conventional DSLR, that's the best way I can describe it.
--The ability to peel back shadows in PP with this sensor is fantastic, just as you would expect from a Sony sensor.
--The articulating screen is the best of the articulating screens I have used (T4i, 60D, A6000, A7R). I have shot with the screen contorted much more than I thought I would, great tool.
--EVF is fantastic, Sony has spoiled me since coming over from my 60D/6D combo.
--If I could only pick one of my cameras to use for everything, I would chose the a77ii. Joystick, top LCD, FPS, AF system, video, menu, durable body, IQ--it is the complete package
As Med Man said, the buffer takes longer to clear than a 7D series would. I haven't shot much at high ISO yet, but seeing what Med Man has done at ISO 6400 with his new PP software it is only a matter of time before I buy it.
