This has got to be the most interesting statement about Pentax lens design since the famous (at least to me) design philosophy document about the FA Limiteds.

Lessons from a Legendary Lens Designer | Photographic Ideals, Basic Principles | The Northcoast Photographer

Pentax for the FA limiteds design for real world rendering that rather than looking at optical test charts looks at the overall rendering. This explains a lot of how modern lenses look sharp but feel weird. Our eyes are sensitive to red and not blue and so I wonder how lens manufacturers prioritize one design idea (blue channel sharpness) over another once we switched to digital sensors.
