Well, f/8-ish should be giving you lots of depth of field, so that is probably not the problem.

However, at f/8 if indoors then your shutter speeds could be low enough to start worrying about motion blur, both camera and subject.

Another aspect is your post-processing settings regarding sharpening.

It is highly doubtful that the problem is related to any sweet spot of the lens. Can you post an example or two, unedited with all the EXIF data intact? That way we will see what you are seeing.
