If you are starting out, you may want to look at the NEX6, you can get one for less than both those cameras, then get a decent prime lens. I think the NEX6 is a better camera than the a6000, the a6300 is a big step up, but it will cost you. If you're just starting out and you're looking to save $$$$$, the A7S is not the way to go right now. These are great cameras and once you get one, you will be hooked. I have the NEX6 and A7S ii. I was going to replace the NEX6 with the 6300, that was until the a6500 came out, never considered the a6000....Good luck with what you decide to do.
