That would also be true with analog film when you start reaching the film grain size.

I'd be curious about the fidelity floor in analog vs digital optics.

I'd guess(?) that you might be able to do more information reconstruction from analog + lense parameters + film parameters than digital + lense parameters?

Simply by virtue of digital being quantitized at some point.

(But signal processing is far outside my area of expertise, so honestly curious)
