I recently bought a Panasonic GX7 and this new Sony wouldn't have changed my mind. I moved to micro four-thirds for good-enough image quality in a much smaller system. The A7 doesn't change that calculation for me. On our recent vacation, I walked around every day with my 14-45, 9-18, 20 and 7.5 fisheye which all fit in the small camera compartment of my Lowepro Photo Sport 200. And I still had room in the camera section for some non-camera gear. Despite the removal of the mirror box, I don't foresee a similar A7 kit occupying the same space.
