Late Autumn Lens Test

I was given a Sigma KA Mount auto focus 28 - 80 mm zoom, pretty much new condition in the box.
Today was a beautiful day, and I went out to test the lens with my Pentax K100 D digital body.
Main location was Pleasant Valley Nature Preserve, which was Girl Scout Camp Hi-Di-Ho some years ago.
I thought the lens was mostly "acceptable," but I do not think it is as as sharp as my Pentax made zoom lenses.
Macro shot of the moss and fungi shows some problems when wide open in Macro mode.
