Sorry I didn't follow. I was looking at the height covered by the off-axis rays at entry.

I'd say it's more relevant to look at how much of the (physical) aperture is used up by the bundle of rays.

hmm I think that is not telling us how much of the incoming rays made it to the sensor.

Here is an image from goptical:

This illustrates more clearly what I was trying to say. How many of the incoming off-axis rays end up on the sensor. I guess that with wides this is often like above, but if we compare lenses of similar focal length and there is a difference then, would this not indicate the light gathering ability of a lens?
