Suppose the MFT user can take a certain photo at 25 mm, f/2.8, 1/100 s, and ISO 3200. To capture the same photo, the FF user needs 50 mm, f/5.6, 1/100 s, and ISO 12800. Do you get it?

Have you tried varying shutter speed and leaving iso untouched?

If the MFT user needs 1/100 s to get the shot right, the FF user would need the same, right?

No, wrong. You want to change the aperture to 5.6, so a photographer will do what they have always done: longer exposure. Of course you could also play with sensitivity - that will depend on the actual picture you are trying to take.

Like I said, too much equivalency clouds the mind and blinds it's practioner to even the most basic things in photography.

I think this equivalence back and forth is beginning to cloud all our minds

I don't have much trouble with it actually. Sorry you do.

You might want to reconsider that in light of the above.
