    Clearly a variable curved sensor such as this would be intended for a mirrorless camera , as no mirror would be able to autofocus a camera using this sensor

    There’s talk this sensor might be destined for surveillance cameras and not mainstream.

      Why would a survielance camera with a fixed lens in any way benefit from a variably curved sensor
      It could only be for an ILC camera and it could only be for mirrorless
