Could you share a bit more what that Intelligent ISO does compared to the plain Auto ISO?

my habit had been to shoot aperture priority and fix the ISO

I have my cameras on auto-ISO, limit 6400.

In general, it keeps my ISO lower than Auto ISO does, and I'm hoping that it therefore reduces noise.

That would be very interesting. I don't quite like why Panasonic first adjusts ISO before aperture.

Intelligent ISO detects movement - or the lack of it - in the subject and decides that if there is little or no movement it does not need to use a fast shutter speed and so keeps ISO low. Auto ISO simply reacts to brightness and I think it allows for both a varying ISO and a varying shutter speed, which is not likely to be optimum.

I hope I'm right and I hope someone else can add a better explanation.

Thanks! I'll have to play with it a little bit I guess.
