later edit: I just found that the "zoom shoot" script does something close to what I want.
It's basically a script proposal I guess.
As the A-series have an electric motor for zoom instead of a manual one, it's hard to zoom in and out when you're taking pictures at short intervals.
A script that would zoom the camera in multishot would be nice
example of sequence for the camera to follow in the script for an approaching subject:
calibrate + shoot -> zoom out x steps -> calibrate + shoot -> zoom out x steps
and even have options to freely add "zoom in"s or "zoom out"s in the shot sequences would be nice.
or perhaps a variant would be every time you press the zoom button, it first takes a picture and only then zooms.
(moderated edit: Added "Lamp" message icon for easier finding later of useful working scripts.)
