flash socket for shutter feedback ?

[laurb9]

Investigate if it's possible to use the flash hotshoe for shutter feedback.

This allows figuring everything out from a test shot.

I’m in the process of designing a gigapixel head myself. I have had luck creating a closed loop system using a Sony A7RIII and a Vello hot shoe adapter like this Vello Adapter in order to detect when the exposure has finished and signal the head that it’s ok to move. It protects against a motion blurred pano having forgotten to match camera and head exposure duration in the menus. It’s also a big time saver for HDR. It gives you tighter timings instead of wasting time during shorter exposures having to account for your longest exposure in a set. I agree it would be great to also get the lens focal length settings automatically but my fix is a simple interrupt edge detection rather than decoding the Sony flash protocol.

This issue was indeed about the standard flash "switch", the other one you are referring to about decoding protocols is probably #55. Did you find that the duration matches the exposure time ?
