unimpressed by my new G28


yesterday i received a G28 and performed some tests against my Sony E 18-55, which left me quite disappointed and i would like to hear your opinion on them, especially from owners of the lens. are there any major flaws with my testing? do i have a bad copy?
First my testchart (i took several pictures at each aperture, and chose the one with best center performance):

Center


Midframe


Corner


the more important infinity test:
Center


Midframe


Corner

using my usual resizing script i don\'t see any difference in the rendering




two full resolution images:
sharpening (50, 0.7, 50)
Sony E 18-55 28mm f/8
G28 f/8

sample image to show the G28\'s field curvature

Of course this short test can only be a first step towards leaning to know the lens and forming an opinion about it, but i think i expected a more impressive performance.
