Sigma 8mm fisheye revelation

It was purely by chance that I was reading a thread on www.dpreview.com about fisheye lenses when I came across a message from "kli" telling me something that was to make my day - the following photos speak for themselves.

I had a look at this lens in a photo store and the salesman also hadn't realised that the collar came off!. It seems that the collar is necessary to allow the lens cap to be retained without touching the front glass. Not sure but it could also be used to support a filter if you accepted the vignetting in the image. I am thinking of buying this lens but will wait till I see the new 4.5mm sigma.
