I learn by "concrete proof in the pudding"...there is none for the FZ200 being diffraction limited at f/2.8...

But if it was (for example in the center of the image), then that would actually be a good thing! If a lens is "diffraction limited" (has its peak resolution) wide open, then that just means that it's a very good lens without any significant aberrations, where the resolution mostly will be limited by the unavoidable diffraction.

IF or CONCRETE...I'll stick with concrete...and the fact that there is no concrete proof...

So, if Panasonic came out with a successor to the FZ200 and the succesor were the same camera in every way except that it had a new lens that was "diffraction limited" already at f/2.8, which version would you prefer: the old one or the new one?

Though, maybe Panasonic shouldn't use the term "diffraction limited" in the advertising.
