First, I'm not sure what the issues are, they seem to me to be consistent,
in the case of the notebook, with depth of field, the near corner is too
close to be in focus, the far corner, too far to be in focus, if you were
using a large aperture.
The wedding image, I dunno. I'm seeing subject movement, camera movement,
and general lack of sharpness. 1/80 sec is too slow for good capture of
moving subjects, and sometimes difficult to hand hold at that slow of a
speed, too.
That being said, we sold our 28-105 f3.5-4.5 because its weaknesses were
made obvious with the 20D in a way that it never was with film or my wife's
10D. If that is the lens you're using, it could be the issue. If you are
using the 28-105 f4.5-5.6, then that definitely is the problem, that lens
has a horrid reputation.
