Firmware details according to Panasonic Japan leak and 43rumors:

  • L Monochrome D – (GH5 / GH5S and G9)
    • “L. monochrome D” Photo Style – Emphasize highlights and shadows, you can take pictures of tasty monochrome photos that exquisite detail
    • Vectorscope can be displayed during WB setting.
  • Grainy” Photo Style mode that can express the texture of an analog-like film Monochrome film – “Granular” mode that expresses the texture of the photo is installed in the image quality adjustment of the photo style. Analog-like random noise can be reproduced and new accent can be added to monochrome photograph. The graininess can be selected from 3 levels, and it can be finished in black and white photography according to preference and world view. Apparently this grainy mode can be adjusted with “monochrome” “L. monochrome” “L. monochrome D”.
  • Added “Focus ring lock” function to disable the focus ring operation and fix the focus position on the custom menu.
  • Added a function that allows you to change the setting while “pressing” the WB / ISO / exposure compensation button.
    • Users can choose from the custom menu.
  • “Dial” was added to “Operation lock setting” of the custom menu.

Improvement of autofocus performance

  • Improved AF performance under low light environment and low contrast environment.
  • When using shutter speed in angle display, AF speed at 180 ° setting was improved.

Improved audio performance

  • Optimized the noise reduction performance of the internal reference microphone and improved the voice quality.

As a GH5S owner, I am looking forward to the new monochrome setting although I am not sure if I can use it in video. I mainly shoot in Natural (custom) or V-Log L with third party lenses, however I am keen to try also the new AF improvement as the GH5 and GH5S definitely needs this in video mode.
