>>3291961There is nothing wrong with the current line of a7 series. The button layout is great, and almost everything is customizable.
Their older NEX, earlier a6k, and even the first gen a7 were kinda rough though. The NEX due to a flat lack of controls, and the a6k due to convoluted menus (though not much of an issue with their FN quick menu, though it does take time to set up).
