And an f2.8 lens is an f2.8 lens in terms of exposure.

t-stops are not f-stops

Yes but on a good prime lens the t-stop should be close to the f stop - regardless of whether it is a m43 lens or an APS-C lens. In practical terms if I am for example taking photos of a gig, I get pretty much the same f2.8 1/125 and ISO 1600 exposure when I switch between using my dslr and m43 camera - which is all that matters to me as I want the shutter speed to be 1/125 and to keep the ISO at 1600 to get the shot(s).

Why would you want to keep the same ISO on both?

Sorry should read 'keep the ISO at 1600 or less' - as in not wanting to go higher and increase noise. I am just saying if I point the 2 different cameras both with 2.8 lenses at the same scene I get the same exposure.

Yes, but different total light and different noise. The bigger system allows you to chose a lower exposure and get the same noise.

So in the hypothetical example given I get the same 1/125 f2.8 ISO 1600 photo. It matters not which one I use as both will pretty much do the same job aside from a small difference in depth of field.

... and noise. If you are comparing m43 to crop, the difference is small but still there.
