The Q Has that as well -it is a physical filter built into the kit lens
and the zoom but not hte toy lenses. I assume it is to allow large
apertures in bright light.
The Q has a maximum shutter speed of 1/2000. The sunny 16 rule would
suggest that at ISO 125 (the lowest the Q supports) a shutter speed of
1/2000 would correlate to f 5.6. Any more open aperture would be over
exposed (if the rule is valid). The 2 stop ND filter would allow you to
shoot in full brutal sun at 1/2000th and f 1.9, should you want shallow
depth of field. It also accomodates the f 2.8 - f 4.5 aperture range on
the zoom. The toy lenses with fixed apertures are not fast enough to
ever need the ND filter, so they don't have them.
And you can get more creamy waterfall shots as well...

It's a P&S camera with a fast (f/1.4-2.7) zoom.

What puzzles me a bit is the footnote next to the max aperture under
"specifications" tab:
"Please Note: Built-in ND filter".
I know what a neutral density filter does. But I wonder if it is
permanently build in (to cope with the huge amount of light, while
allowing the shallower DOF), or it moves in under certain condition.
The latter sounds like a big mechanical complication to me, while the
former defeats one of the purposes of having a fast lens.
Any thoughts?
I am considering this or Lumix LX7 as a possible "pocket camera".

That camera has a slightly faster, f/1.4-2.3, lens with a slightly longer
reach of the zoom (24-90mm equiv vs 24-80mm).

PS. Lumix LX7 has a funny footnote about the lens:
"One Nano Surface Coating Lens"
