It sort of hits a few buttons for me, I could keep my a7r2 and finally ditch my a6000 as my 2nd camera which I rarely use unless I'm desperate for longer reach. The EVF is a bit better, the AF will be alot better, don't really care about the cards, or their speed to be honest. Articulating screen and touchscreen is an improvement, though Im an EVF guy. I might need to change that as
I don't see anyone using the EVF now, I was out with a group of around 10 on Sat night and I was the only one using the EVF which made me think a bit. I think I would still need it for vintage lenses, can't imagine doing the zoom in to focus on the screen rather than the EVF.
I have no idea what the jump down to 33MP would be like compared to my A7R2, that is something I can't really get my head around, less room to crop, but otherwise would it be noticeable? It just feels like a drop from 42MP to 33MP would be a downgrade and I don't think that feels right to me, though of course it would be a massive upgrade from my a6000
