Hi,
Any lens that can produce moiré outresolves the sensor, and a lot of them do. Most lenses are pretty good near centre when stopped down to best aperture. It is good corners we are paying a lot for.
Ideally, the sensor would outresolve the lens, so it would capture all detail the lens delivers correctly. The result would be bad pixel-peeping on screen but great if downsized using a proper algorithm.
The image below shows a lot of artefacts, with twice the resolution it would look natural. Jim Kasson made some analysis and arrived at 100 MP or more needed to make best use of an Otus.
If we assume a lens that has it's best performance at f/5.6, I would say that we need something like 2.5-3.0 Micron pixels to avoid aliasing, so that would be 100-140 MP. The Sony RX-100III has 2.4 micron pixels and does decently well, although having a very small sensor, 8.8 x 13.2 mm.
Best regards
Erik
