Not to mention that the lenses referenced like the RF 100-400mm, the 600mm/800mm and others are not all that bright. If one says the 17-55mm f/2.8 wasn't fast enough for them then how can 600mm/800mm lenses at f/11,and the RF 100-400mm, be something they can recommend? Especially on a crop camera where the use cases for a f/11 lens is so narrow it makes them almost unusable. Even the RF 100-400mm is limited on a crop camera.

Why does the aperture being F/11 make a difference on a crop vs a full frame? It will focus the same, just using the inner 1.6x of the lens.

I assume most buying the 600 and 800 are wildlife / bird photographers where you are outdoors anyways.
