I agree if i needed higher than ISO 1600 cam I would be looking at a D4 or similar or even the new A7s but more my intent on the A77II was something i don't get on the A7/A7r is the AF speed and tracking. This will do exactly what I need for PR work and more important and a big money income for me is the runway stuff that I do for my wife's company I need a 300mm effective and focus tracking to nail models going down the runway which typically is about ISO 1250 so investing in the 3rd body is a no brainer for me, As it does exactly what I need and the A6000 is a close second but no vertical grip makes it impossible to shoot 15 thousand images with my hand over the camera. I can't do that physically as my arthritis kicks in almost immediately and I can't move my hands. So i have to have a vertical grip on those gigs. Having the A glass makes this cam a bonus in my system. Is it perfect no its not but if you need AF on a cam this does have some real power to it.
