So, if I had my 75mm f1.8 on my E-M5 and was using a light meter which told me to set the aperture to f1.8, what would I set it to?

I'm sure I can't speak for what you would do.  I could tell you what I would do, if you like -- let me know.

In any case, neither here nor there, in terms of my post that you were responding to.  That is, 75mm f/1.8 is 75mm f/1.8, not 150mm f/1.8.  However, 75mm f/1.8 on mFT is equivalent to 150mm f/5.6 on FF, where by "equivalent to" I mean it has the same diagonal angle of view, the same DOF for a given perspective, framing, and display size, and projects the same total amount of light on the sensor for a given shutter speed, resulting in the same noise for equally efficient sensors.

Now, if I've guessed correctly, you don't care.  No problem, but you did respond to my post, and, well...
