Some test shots taken with the Pentax DFA 100/2.8 Macro. I had this lens for a day, then took it back. Wish I kept it.
The first 2 are at minimum focusing distance (1:1) broken screw that is 6mm (1/4") across.
The second 2 are showing the out-of-focus (bokeh) characteristics.
These images were hand-held in low light (the bokeh images are 1/6 ~ 1/8 second!) and converted in-camera to low-res JPEG's, so take these images for what they are worth.
