I have a A6000, and the back and front of these Nikon's looks very similar to it, and Sony's in the A7 series too. The flippy screen, the top plate, even elements of the front grip. In design terms, they have essentially grafted a few Nikon buttons onto a Sony body. Not a criticism of either manufacturer - the design choices work OK (except for the lens mount button).

I have a few Nikon's at hand. These mirrorless models just won't feel the same - the smaller size is just never going to deliver the same hand-feel as a regular Nikon DSLR. Button placement is also clearly more squished up on these mirrorless bodies.
