Here are a couple unprocessed photos from this lens. The first one is handheld leaning up against a tree. f/10, 1/5 sec.

The macro on this lens is ok. Minimum focus distance is close but the autofocus has problems real close and it's hard with manual focus to get it just right. Anyways this one turned out pretty good I thought. f/7.1, 1/800 sec.

you lost sharpness in the whole image due to camera shake.
