Has anyone seen an f/1.4 lens beat an f/4 lens at f/2?

That's an old chestnut - they all would.

The even older chestnut is that f/8 in the centre is where
even less than stellar lenses are usually very good.

Oh, and that many people don't want to use only f/8 and the
centre on a D800.


(How do you stop UP an f4 lens?)

I don't know what you'd do it, *I*'d use a focal reducer.
