Manual focus not implemented for Sony ILCE-7M4 (Alpha 7 IV)

[Ryther]

Describe the bug

Looks like that the Sony ILCE-7M4 does not have manual focus settings, but the camera's focus can be managed remotely with Sony's Remote Camera Control.

Name the camera
Sony Alpha-A7 IV (PC Control)

The latest version of the repository was built, since the camera has the infamous type 300 bug.

Thank you for all your hard work!

i checked the Sony SDK, Manual Focus is not supported on the ILCE 7M4.
