    Detail

    Firmware Version 1.1.2 incorporates the following enhancement:
    1. Increases the manual focus speed when the manual focus speed switch is set to 1 or 2.
    *The speed when the switch is set to 3 (slowest speed) will be unchanged.
    2. Improves the image stabilization effect during handheld shooting with a slow shutter speed when used with EOS 5D Mark IV, EOS 6D, or EOS R.
