Sony ILCE-7RM2, unable to read or set capturetarget

[lidar532]

Bug description

I'm trying to get the camera to simply take photos to the SD card, and not attempt to send anything to gphoto2. I'm triggering the camera externally at 1 Hz, and simply need to capture the photos to the 512 GB SDcard I have loaded. My goal is to use gphoto2 to remotely control various camera settings such as shutter speed, ISO, Exp. Comp, etc. The camera will be located in the wing tip of an aircraft with no access while in flight.

To do this, I attempted to use:

gphoto2: {/home/wright} /> set-config capturetarget=1

*** Error ***
capturetarget not found in configuration tree.
*** Error (-1: 'Unspecified error') ***
gphoto2: {/home/wright} />

which failed as shown, as did:

gphoto2: {/home/wright} /> get-config capturetarget

*** Error ***
capturetarget not found in configuration tree.
*** Error (-1: 'Unspecified error') ***
gphoto2: {/home/wright} />

Only some newer Sony allow capturetarget selection, others support only SDRAM capture.

The property in summary would be 0xd222 , which is not in the list here.

So I think the 7RM2 is one of the sonys not yet supporting remote capture to sdram.

You can check the menu in camera if it offers this perhaps, but its seems not visible over remote.
