Toni, again, not everything is opinion. What I wrote about is just plain facts, based on the physics of light. Not my "opinion". Mixing up facts, not understanding their their context, and making your own supposition based on the incorrect understanding can or will lead to an opinion not supported by facts anymore. Like taking resolution numbers from a single colour from the visible light spectrum (a blue) and then saying those are the diffraction limits for photographic lenses.
