Prob know the answer, but…

…what do we think the prospect of retrospective focus bracketing being made available in software updates for A7IV and A7III bodies? That’s one feature I do miss from lumix days albeit theirs was a video from which (low res) images could be extracted.

Breath not being held

If its not the current line-up, don't expect a software update. That rules out the A7III. Heck it even seems like Sony's [sparse] updates are only made within 6 months of releasing the camera, then they move on. Not an evidence-backed claim, just feels like it.
