I’m thinking through what lenses to purchase for my R series Canon. While the 2.8L lenses are optically superior, the 4.0L lenses are still very good and less expansive and heavy.

Under what shooting conditions will I see the difference in quality between one line of lenses against the other line of lenses?

in my experience, i owned 70-200 f2.8 non-IS and 70-200 f4.0 IS, and to be frank, i much preferred the f4.0 IS quality, no doubt about it. the fluorite element in f4.0 IS is doing magic. But, the f2.8 mk3 has 4 fluorite elements so i can imagine the IQ of this lens.
