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.

Why not? "Limited" seems to be a rather viable term in marketing speak. Certain Pentax and Oly lenses come to mind for example. And "diffraction" sounds rather advanced, doesn't it. Besides, Canon is already using the term in its lens marketing. Diffractive optics. Great stuff.

Panazonic FZ200 Diffraction Limited. We've already got the name for them.

Not at F/2.8...and probably not until f/3.6...

Whereas the phrase "Diffusion Limited" might be more applicable to debates, the phrase, "Phased Array Linear Dispersion Orthagonal Retro Rockets", always has had a rather sexy ring to me.

Must I keep repeating:

"inebriated by the exuberance of their own verbosity"

Lol...

Mr Ichiro Kitao, I support the call to upgrade the FZ50.
I will not only buy one but two no questions asked...
