On the same format.Did you leave that part out on purpose? Has anyone tried to say that's not the case?

By the way, are you still trying to claim that cropping FF and displaying at the same size as before does not change DOF, or have you moved on to something else? I'm confused about what point you're trying to make with that link.

The point is that a 300f2.8 lens is a 300mm f2.8 lens on any format camera it characteristics do not alter one jot it behavior is not altered by what subsection of its protected image the sensors captures the-fore cutting that same subsection out of a larger sample will deliver exactly the same image as the smaller sensor would have captured DoF and all.

You perceive them to change  because of the different viewing size (i.e magnification).

But your exposure will be the same and hence you have more reach on smaller sensors there is no magic FF formula .

Voff pointed out you were breaking the laws of physics to make your claims, I've simply presented the physics.! (repeatedly from multiple sources)
