Comments:

Focusing can be done on objects that are only mm away. This leads to my biggest concern when using this lens: the danger of hitting the object that i'm focusing on, resulting in a scratched front optic. So far, I have had a lot of fun photographing every day items resulting in unusual results. The main draw back to this lens, in my opinion, is that it is very pricey for what could be considered a "novelty" lens. Initially, I thought that I might return it, but have become hooked on trying it when I'm taking pictures. One more item to drag around in my camera bag.

Comments:

Image quality is superb, the contrast pleasantly surprised me. Even at f2.8 I do not see vignetting worth noting in the area of view - however, most of your image is of the barrel. I was surprised at how small the image circle, probably only 1/3 of the view finder is filled with the circle of view. I may yet return this because by the time you crop the image to get a print there isn't much resolution left to play with.
