High-Resolution mode for Cinema 5k and 16:9 5k.

48fps - very odd that hasn't made an appearance on the GH5s either.

My updates, which I would like to see

1. Rear/Front Dial locking - function available on the G9
2. Visible ISO, Aperture, Shutter values when using a Program mode
3. Ability to perform AF-Lock before recording in VFR (So at least you can AF sort of)
4. Ability to assign the control dials, jog dial to SS, Aperture or ISO, in any order you require
5. 48fps with sound and AF (non VFR)
6. True 'One-Touch' Manual WB. Point at subject, press Fn button and hey presto white balance is set and you are ready to shoot (without have to do WB, Up, Set)
7. Ability to toggle HDMI Info overlay On/Off via an Fn command
8. Standardise the menu system of the GH5 to incorporate the menu layout improvements from the GH5s
9. Instead of the Flower / Mountain MF Scale, provide actual Mts/Ft where the focus is
10. If using a program mode and if the camera is unable to provide adequate exposure, display the actual exposure reading (-3 on the scale for example) and not just -/+ icon.
11. Add the option to display both Degrees and Gain at the same time instead of ISO/SS

-showing exposure info in video modes (aperture,ss and iso)

-HLG profile in 8bit modes too (4k60P).

-slowly blinking red recording dot should be fixed

-6k photo with 16:9 ratio and working AFS

In camera 10bit 60fps, 240fps @1080 in crop mode, 10bit 4k HEVC in camera codec and Free V-Log, I guess if they are asking for realistic suggestions these can be implemented by Panasonic.
