I'm not sure this isn't a product of how large and optically uncompromised the 4/3s zooms were. It's hard to correct a lens as fully when compactness and light weight are leading priorities.

Large? I don' think they were too large but I agree that maybe we as users did not appreciate fully how good those lenses were.

Compare the size of the Oly 4/3 7-14 to that of the Panasonic m43 7-14,

A lot of the size savings from the 7-14 seem to be due to the mirror box in this case creating the need for a more complex design... Also the Olympus seems to have little to no issues unlike the Panasonic lens which has had a number o fhtreads about purple flare?

The purple-flare issue is due to the fact that a) the antireflective coatings on at least some of the lens elements of the 7-14 do not fully remove reflections close to the border between ultraviolet and violet and b) the on-sensor UV-filter on most/all Oly bodies, unlike that in most/all Panasonic bodies, does not eliminate these wavelengths. It has nothing whatsoever to do with the issue discussed in this thread. See here for additional details:

14-35/2.0 to the 12-35/2.8,

Software correction and a 1 stop aperture difference... Also the 12-35 doesnt even compare well against the 12-60 43rds lens for sharpness, let alone the 14-35.

What directly comparable evidence can you muster in support of your claims regarding sharpness?

There is no free lunch, software correction and slow apertures will make smaller lenses. These smaller lenses will not outperform larger lenses for IQ reasons, they will have different advantages (size portability, comfort in use, price etc.)

What evidence can you muster in support of your claim that the smaller lenses MFT lenses cannot outperform the larger FT lenses, everything else equal (including max aperture).
