Mostly non-functional with Sony ILCE-7C #946

Closed BenLand100 closed 6 months ago

BenLand100 commented 6 months ago

I use this camera for astrophotography, and ultimately ended up here after Kstars/Ekos identified a "lack of exposure widget" for this camera as being a gphoto2 error. After debugging with gphoto2 CLI a bit, it appears my (?) ILCE-7C doesn't have any significant functionality, despite being listed as supported by gphoto2. Any idea how to get to a more capable state?

I assume this is not an issue with my camera, as the same cables+camera work fine under a Windows ecosystem also using Sony's PTP https://github.com/dougforpres/ASCOMSonyCameraDriver

Things to note:

Basic capture functionality errors out, camera does nothing:

benland100@blandtoo ~ $ gphoto2 --capture-image
ERROR: Could not capture image.                                                
ERROR: Could not capture.

Curiously, --trigger-capture works, as in the camera takes a picture successfully, but the command itself fails:

benland100@blandtoo ~ $ gphoto2 --trigger-capture
ERROR: Could not trigger capture.                                              
*** Error (-1: 'Unspecified error') ***

There are not many config options showing, though I can adjust e.g. whitebalance with --set-config and --get-config and these seem to take effect on the camera.

Looks like the fix for #937, which is already in the repo, resolves this, it's just not in the most recent release yet.

msmeissn commented 6 months ago

yes, will be in next release
