However, from that point of view, the sampling rate is much higher with film than with present-day digital camerae, and the sampling rate is more random, so that obvious effects, such as moire patterns, are less noticeable. > limitations and can utilize better optics. > > The rest is OT...

I usually use the term "pragmatically," as in film pragmatically doesn't suffer from "digital's" nyquist limitations. But I guess one can split fine hairs and say Nyquist applies to everything. The fact though is most digital cameras can't capture those fine hairs because film (depending on granularity/resolving power) has so vastly higher a sampling rate when compared to digital you have no need to dumb down typically used optics or otherwise reduce the scene signal frequencies to prevent moire and artifacting. |
