Hello,
When I use my Sony A7iii and Ronin-S I can get the focus wheel and rec/start stop to work with both the MCC-C abd MCC-Multi Cable. (Multi controls zoom)
BUT when I use the MCC-C cable (which gives control to focus wheel) and have PC remote enabled the HDMI sends a black image. It seems to be a Sony issue but wanted to see if anybody have found a work around.

I am trying to get control of focus wheel to control lens focus and have HDMI out work.

Thanks

Have any one figured this one out?
Does the Sony camera A7iii work with MCC-Multi cable input and the HDMI-output to a monitor simultaneously?

Thank you for your replay, XinRain.

However, your solution does not work for me.
My external monitor still goes black even after selecting off on HMDI info, and then connecting the cable to the camera. I can pull focus with the USB-C Cable with no monitor connected, but filming outdoors I would like to use my external Atomos monitor as well.

It`s a Sony problem. Because the camera selects the USB over HDMI-output, and it cannot do both at the same time.

Ronin S:
Second last firmware, NOT the last firmware. (Because the last firmware there was something wrong with it)

Since i bought it i've never had updated the firmware on the camera.

It just baffles me that it works for me though.
