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?

Lots of people have pointed out the extra light gathering ability. I will add that if you are shooting still scenes the IS, perhaps combined with IBIS depending on which R camera you get, will help you out in low light, perhaps enough do that you won’t need the extra stop of an f/2.8 zoom. Of course, the IS helps the faster zooms too. The RF faster zooms are lighter than their EF equivalents. If low light does not matter that much the f/4’s are just as sharp as the faster zooms.
