Thank you for collecting all that information, photonius.
It certainly seems to point to the fact that UV-filters do not degrade sharpness.
Kind regards, Wim

I have seen lots of empirical claims, in particular for the 100-400 lens, that this has issues with filters,
claims range from bad bokeh, affected AF, softness, even with good filters. but no serious test.
But generally, tele lenses would be more susceptible to flaws in the glass, so there may be something to it.
