Speaking only from a technical perspective, I remember a that a few decades ago a photo magazine had an article about reaching 100 lines/mm resolution. (In this context, 100 lines/mm means 100 dark lines interleaved with 100 light lines, i.e. line pairs.) In fairness, they used a high contrast target, and resulting 100 lines/mm image was basically at the visible limit, i.e. low contrast. I think the film was Panatomic-X, which isn't made anymore.
Anyway, They were able to get very close to 100 lines/mm with with a number of lenses when used at optimum aperture, and they even reached that level with a few lenses.
There is something called the Nyquist sampling theorem, which states (in the case we are discussing here), you need at least 200 sampling points/mm to resolve 100 lines/mm. What does this imply? It means that you would need at least 34,560,000 image sensor, i.e. about 35 Megapixels for a 24x36mm image, i.e. a 35mm image.
How does 35 Megapixels map onto current technology? It means that with a 70 Megapixel camera you could come close to resolving 100 lines/mm.
I consider that 1% figure given by Fuji for their colour film sales very plausible based on the figures I got.
So basically everyone is increasing their prices?
1. The BW fundamentalism...
There are hundreds of thousands of it...
And their behaviour is of course severly hurting Fuji and Kodak.
We all know that you don’t have any real sales figures from Fuji at all.
We all remember very well that just some time ago you said here several times that there is no Fuji Instax film revival.
You do not even know who I am, except for trying some idiotic guesswork.
I did NOT say there is no Instax revival.
I seem to be on an off-topic tear lately, but here goes anyway.
On October 6 2015, George Eastman House changed its name to George Eastman Museum. Yes, Ron, I know, old habits die hard.
You've doubled twice. 200 pixels/mm to resolve 100 line pairs/mm (please don't say lines/mm when you mean line pairs/mm) at the Nyquist limit gives a 4800x7200 pixel grid for 24x36 mm sensor size, or 35.6 megapixels. Not 70.
Hello,
Concerning the resolution topic discussed by some members here above.
I am doing lens, film, developer (and lately sensor) tests for more than 20 years now, on a scientific basis....
Yet I'm disappointed that on digital photography forums the belief is that "a 6MP camera matches 35mm quality". They think common 16MP and 24MP cameras are capable of far superior image quality and that with the high-end 36MP, 50MP cameras, there is no contest at all.
[...]Henning,
Very impressive to see these details.

Aren't there quite a few on APUG who also believe the same from posts I have seen?

when Fuji's digital execs talk about about film, then mostly......much ado about nothing.
There is a long history over the years that these guys are not very well informed (I am also talking from my own experience with some of them...).
P.S.: Concerning the just announced Fuji price increase: Kodak will increase prices, too. 15%, from February on. Source: One of the biggest worldwide online film distributors. An absolutely reliable source.
You are hiding behind your "AgX". You don't have the honesty to show who you are.
No one in the industry knows an "AgX". You are not existent for anyone there. No one knows you.
Yes, post #32, or just page 4 to 6 or so.
No need to go to D forums, we got inexperienced darkroom virgins in excess on APUG.
good full frame DSLR will just plain spank any 35mm film... by Roger Cole
Roger is not alone, there are thousands of threads full of humor and digital bliss.

A while back I put together a really long, beautifully written post on why much of the problem with these discussions is that inevitably people compare the results obtained using purely digital equipment with the results obtained when a film image is converted to digital.
Really, it was beautifully written .......
Of course, that particular thread blew up, and was completely scrubbed from the site.
I have friends that have gone the other direction. They invested in equipment that converts digital files to film transparencies or negatives.
In either case, the final result suffers, because the conversion process isn't perfect - you just cannot do it without losing something.
That is not to say that you cannot obtain fairly high quality, and add other desirable attributes by doing the conversion with high quality (and relatively expensive) conversion equipment and procedures.
Especially when you consider the incredibly low prices for really high quality film equipment, vs the relatively high prices for middling quality amateur digital equipment.
But if a significant portion of your process involves digital techniques, than a completely digital workflow will have an advantage.
And if the most significant portion of your process involves analog techniques, than a completely analog workflow will have an advantage.
Except one thing: what Roger said there is fact. Enjoy.
It's still digital imagery but if you are blind enough to enjoy it... keep up it up.
What kind of traditional photographer is presenting scanned film as fact?
How dare you guys calling yourself film photographers?
You can put me and Henning on ignore list or call us film extremists but where is the ignorance list, so that we can put you where you belong?
what does any of this have to do with " Fujifilm Exec's talk about Film " ???
...
its nice to see such insulting, open minded people on apug !
who cares about any of this film vs digital BS ..
