Can someone please take a look at these test images (from my Powershot A75) I took and tell me whether the somewhat blurriness mainly in the corners (also see the right side of some of them) is normal or not? Some of the images seem fine, and some seem worse. I may be doing something wrong with the camera, since I'm just an amateur, so any advice would be appreciated. (I tried to keep the page flat in all the pics). They were taken in macro mode.

Also, would these be noticeable in real pics? (not test shots of phone book pages :-) )
Here are the links:

First pic:
16mm,F/4.8
Second pic:
5mm,F/2.8
Third pic:
5mm/F2.8
Fourth pic:
5mm/F2.8
Fifth pic:
5mm/F2.8

Here is the same pic with the focal length kept at 5mm, but varying at F/2.8, F/3.5, F/4.5. and F/5.6 respectively:

I think that the images seem to get better at smaller apertures, but I also don't believe that the problem totally goes away. Maybe this has something to do with macro mode? Or barrel distortion at wide angle? Is this normal for P&S cameras? Any help would be appreciated.
Also, are there any other tests I should try to check this out?
