Thanks for your concern.
The calibration does seem to help (slightly perhaps). I have posted one of the test shot
here.
I spoke to a photographer friend and he said that ultra-wide lenses having a 90deg. field of view (like the DA14) can never be sharp especially at the corners. Also, it is not usual to pixel peep into images taken with ultra-wide lenses and we can never expect the 100% crop image to be as sharp as those taken with a zoom lens.
Nevertheless, I have posted the 100% crop of the test shot here for information.
