Quite a rare lens Chiek...I have seen them occasionally appear on ebay from time to time.
Beautiful and unusal bokeh, the lens has some character to it and I wasn't referring to the weight of it.
Strangely I just spotted one on Ebay and suprisingly with an E mount...In case anybody is interested.
Hope this isn't breaking any rules, I will post the link below...It's not my lens or anybody I know.
