I would like you to answer this question, which I have now posed to you three times without an answer:

If noise and DOF do not matter, then what is the difference between f/2 ISO 100, f/2.8 ISO 200, f/4 ISO 400, f/5.6 ISO 800, etc.?

If I say "nothing" I suppose you will go "ha!! I got you!"... but then I clearly said I only shoot at base ISO, so noise is not important to me. I think my original post was clear. At least 14 people "like" what I was trying to show: exposure is exposure regardless of format.
