It all depends on the definition of "noticeable".

With a sharp lens mounted on the E-M5 you can certainly see the effect of diffraction at f/8 versus e.g. f/5.6 when looking carefully at 100% pixel level on a sharp monitor. Does that qualify as noticeable?

I typically view my images on a 1920x1200 pixel 24" monitor. At that resolution and monitor size such measurable difference in sharpness is not noticeable. When I take shots with the 12-50 or 20mm there is no noticeable difference in sharpness on my monitor. When viewed at 100% there is a visible difference, and also a visible decrease in sharpness on the 20mm when going from f/5.6 to f/8. But for practical use there is no noticeable difference.

Most of the discussion about diffraction is about differences and softening that isn't really visible when admiring a photo, only when pixel-peeping.
