Refer back to the video and you will find that is erroneous. The author used templates sized to the different sensor for this test to duplicate the amount of light the sensor receives.
Yes, but as I understand it that's exactly what I said. The template blocks some of the light that the FF lens let's in, replicating the smaller sensor getting less light. The larger amount of light is not utilized.

I recall doing this "comparison" stuff when I was about four...behind the shed with Jimmy, Ronnie and...Oh yes, Karen.
I don't really know where or why a guy with one camera a three lenses can use any of this, much less would anyone I know have time to whip out calculator and perform all of these formulas just to get a pic of the kiddos in the park or at the zoo....just don't see it. (And it really isn't interesting bar talk!)

I am familiar with the current bokeh fad. But when I learned photography we were taught to frame our images without distractions in the background, and I still strive to shoot that way. And yes, when shooting birds and wildlife, that is not possible, but I don't shoot those subjects.
In any case, managing depth of field dynamically is already a problem for anyone using a zoom lens, so managing the difference between, say, 50mm and 70mm should be no big stretch.

DOF is just one part of it. Higher S/N, DR and freezing movement are considerations as well and impact all shooting scenarios.
