B&H interviews Sony's Mark Weir about the new Sony a7S, a 4K mirrorless camera that shares a body (and full-frame E mount) with the a7/a7R but introduces a new 12.2 Mp sensor with large photosites that enable shooting in extremely low light. The camera records HD internally and full 4K externally via HDMI.
