I have been intrigued by this lens for some time. Then I came across with some images of this lens, see "branch" attached image. While the rear bokeh looks awesome, the fore bokeh looks very weird, see "cropped" attached image. You can see clearly the rings and dots in the middle. I am actually dissapointed with this because eventually I would like to buy this lens but now I am having second thoughts. What are your thoughts on this issue?
Note: I am not sure whether the attachments will work?
