As far as I can tell, there are no threads in the gallery about this lens. I don't think it's manufactured anymore but it's widely available on ebay. It's compatible with minolta cameras as well as the sony alpha cameras.

Ive been using it on my a200 for a few months, here are some samples.
The last image of the egret was a crop from a much larger picture. Yet still reasonably sharp. All of these were handheld.[url][/url]
