Thoughts on Moiré and DSLR Resolution and the Optical Low Pass Filter

Moiré should become a non-issue with DSLRs.

With the 36-megapixel Nikon D800E showing really minimal effects of moiré, not even close to the ugly results as shown below with the 18MP Leica M9, my supposition is that the lens as a limiting factor in controlling moiré is already here for most lenses.

Let’s see the move to 60+ megapixels in a DSLR (even if the output resolution is less than that). That should settle the moiré matter with finality.

Remove that superfluous optical low pass filter (OLPF), and forget about moiré— at 60+ MP, the lenses will not resolve well enough to make moiré anything but a faint hint under the best conditions, so a simplified camera design can result.

There is no technical reason not to produce a 100MP DSLR in time, perhaps much less time than one might think. Let it be free of an OLPF, and produce images downsampled to 50MP, free of digital artifacts— oversampling for the best quality at a lower output resolution, as I already demonstrate, from 36MP to 18MP.
