I don't see anyone mentioning the A5100 which is essentially an A6000 but no Electronic Viewfinder (EVF). That makes is a little cheaper than the A6000 even, and then you can buy some good Sony glass. For the extra features though, A7ii is great. IBIS and being full-frame are great for handheld and wide angle or getting a lot more detail vs some crop sensors. I'd lean more towards the A7ii and buy one nice zoom to start with, and as someone else said, Rokinon makes decent lenses on a budget. I shoot on a D3400 and sometimes I wish I had a better body for easier shortcuts to change settings or that little bit of extra width or quality to a picture, though modern sensors are all great even in poor light.
Good luck with whatever you choose!
