Re: To all who think that aperture equivalence is irrelevant

It is relevant because the total amount of light gathered is the single property which explains almost all differences in noise in the full image when you compare modern cameras. So this is actually the reasoning behind my claim #3.

For a pretty damn narrow definition of "modern". For instance, switching to an improved sensor alone made Olympus jump forward in 0.65EV between the E-PL3 and the E-PL5, and even against contemporary Panasonic cameras there's an improvement of around half a stop.

Haven't run the numbers in other segments, but I suspect your data happened to be well correlated by pure chance and that we'd see similar variance in other sensor sizes given enough samples. Except for 1" of course since, you know, there ain't any.
