"4K" simply means 4000 (and 96) pixels across the 36mm film chip. Actually,
2889.9ppi.

Well, when you can perceive no diff on film, what else is logical to believe 
except that
somewhere close to this IS film rez translated to pixel density?
What's higher rez output than film itself?

If you're talking as per digicams, as in your comments below, I agree. But only
because digicams aren't cranking true and accurate pixels (yet).

I can only speak of the films I have personally output and observed, those 
being:
Tmax 100, Ektachrome 100+, and Vericolor III (now discontinued) and Portra NC.
I can perceive no appreciable diff. I'm not saying there isn't some, only that 
11-12MP is
getting pretty close to 35mm rez for many, if not most, common films.

I have no expertise in digicam theory/tech. I totally agree that the pixels 
must be
"real". I can only speak for what I've observed with film scans output back to 
film. I only
have Nikon 2000 presently, which is not up to snuff, but again, the drum scans 
I've
seen are close enough that the "4K" film recording rule of thumb seems 
reasonable.
Again, don't get too hung up on the term, just refers to 4000 (and 96) pixels 
across the
36mm. It seems obvious to me that equal pixel densities from quality film 
scanners
beats the crap out of digicam output at the present time.

Comparing my 3MP toy digicam with even a 3MP scan from film shows the scan to be
MUCH superior, pixel for pixel.

Well, again, that's going quite far afield from the contentions I've made. IF 
(guess I
should say "when") digicams produce the same quality of pixels that film 
scanners are
now doing, megapixel for megapixel, then I still think a 11-12 MP image is the 
"holy
grail" to match mainstream 35mm film use.

I'm quite impressed with the quick evolution in scanner tech, but still quite
underwhelmed with the same in digicams. If I didn't have all my years of 
experience in
film, maybe I wouldn't be.
