When I'm using ACR am I getting automatic corrections or do I have to do
something to enable it? I've never noticed distortion from the 12-50
but then I haven't been deliberately doing rectilinear stuff nor any
testing.

µ4/3 lenses communicate with the cameras, which in turn include data

only addressing linear distortion here.
As I mentioned before, my use of the Panny 12-32 kit lens for the GM1
led me to discover that the built-in correction didn't seem very good
close up.
I recently ran into more such trouble getting an image to look right,
which led me to do some simple testing.

I assumed the 12-32 would be worse than most other lenses, as design
compromises were probably made to make it so small. So I also checked
the M.ZD 12-50. You can see that the 12-50 has less distortion when
uncorrected than the 12-32, but still quite a lot
