So while the "fundamental" statement is correct the reality is that smaller sensors suffer from diffraction at larger apertures than large sensors because we change the magnification of the image captured by the surface of the sensor.

A man after my own heart...common sense at it's best!

So you are starting to see at least parts of the light after all?

I've always had the light...it's the BS one has to filter out...

In short, it is entirely possible for the FZ200 to be sharper at f/4 than it is at f/2.8, even though at f/2.8 it is already well within the realm of strong diffraction softening, and the lesser lens aberrations at f/4 may outweigh the increased diffraction softening.

Regardless, the effects of diffraction softening at f/2.8 on an FZ200 are identical to the effects of diffraction softening at f/8 on mFT and f/16 on FF, it's just that diffraction softening is one of many forms of blur.

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