Yes. And when the pixel count is held constant, the image resolution is about the same, showing that the lenses perform on a par.

There is such thing as analyzing sensitivity, etc. How much difference a much sharper lens will give you nn an 1mp sensor? On a 12mp one, etc.? What does it tell you about the resolution of the lens on a non-existing sensor?

What the formula tells you, and that's clear enough along with relevant evidence like what I posted.

I will not serve as your private tutor on that, sorry. I do this for money.

Don't worry. I wouldn't think of hiring you.

You should certainly hire somebody.

I don't need to hire anybody. But if you need to sell yourself, you have a problem.

Are you saying that his DOF is too shallow for you:

What I am saying is that the fast MFT primes I use (all of which somewhere between f/1.7 and f/2) get me as shallow DoF as I usually want or can accept. In other words, I have sufficient "DoF control" for my objectives and requirements and prefer the additional "FL control" I get with MFT.

Dodging the question?
