Mitigating Color Aliasing via Diffraction (Leica M240, but applies to any/all)
Cameras lacking anti-aliasing filters tend to suffer from color aliasing and moiré. Usually this is not an issue, but it can all but ruin some images. But there is a workaround that is easy and practical for many purposes, with a “balancing point” of best results (sharpness and contrast versus mitigating aliasing).
Diffraction vs Color Aliasing (Leica M240)
This example confirms and expands upon the principles discussed in Mitigating Color Aliasing via Diffraction (Leica S2).
Canon shooters contemplating the 50-megapixel 5DS or 5DS R might find the discussion particularly interesting on the value of 50 megapixels vs 23/24 (Canon 5D Mark III).
