Btw. I have received some questions from people who are interested in the lens and would like to clarify that even though it may look like it in web sized photos it never gets sharp in the corners, even stopped down all the way. It doesn't bother me, but it's something to be aware of. The appeal for me is having access to the special look (blur or swirl depending on the background and optional mechanical vignetting) and its great colors, contrast, sense of depth and sharpness in the center areas. Then be able to get something that looks like normal photos if I feel the scene/subject requires it.
