I wonder if we talking about the same thing. What I was trying to say
is that S16 was primarily created as blow-up only system. And yes, as
such it was to used on regular theatrical ratio, which is 1.85 and
considered wide screen.
When you tried to do that with four-perforation 16mm negative instead
of two-perforation 16mm negative you lost almost half the total area
trying to get the same wide-screen ratio.
That is the blow-up ratio was diminished when using super 16, which
improved grain resolution.

First of all my comparison was not intended to be really accurate,
comparing exactly DV with 16 and HDV with S16. DV never got close to
16mm film in any area and HDV doesn't get there either. But you insist
on comparing 16 with S16. S16 was resurfaced by Aaton in the late '80s
so people would shoot film to be used in later times, when HDTV came
along. And why: because the useful area was larger and filled the whole
16:9 frame. 16mm only did that if you zoomed in the telecine, losing
more than 40% of the negateive area.
What I meant is that DV became the tool of the independent filmmaker,
like what the Bolex16mm had been in the past. And that HDV might well
become what Super16 came to be, bringing the indie into the big movies.
But S16 is on a different league than HDV altogether. To compare S16
you have to go to the Cinealta cameras.

Not necessarily. Even if they were experimental, have you seen the FX1
modified to use fixed lenses, like the Nikon?

Nikon or Canon prime lenses are not that expensive. And they would be a
lot better than the lenses used on these cameras.
The question is that there should be a camera that could let you use
them without any adapters. And of course there's the issue that the
focal lengths should be different for video.

No, I (as probably everybody that goes to a film theatre) like image
quality. Technology is just a way to get there, which is quite
affordable now. There are practical things in video that you can't get
in film. And as you can see film is the reference for everybody. So how
can you live with these technologies? IMHO knowing the limits of video
and playing with them. That I will try to imitate film behavior? Of
course and as much as I can.

I certainly pay more attention than you think I do. But let's leave it
there.
