Rare,,, hardly ever seen in heavy chrome on brass, never mind in Cmt. serial # 3277933. Tested on a lumix G-1 , Not ultra sharp, really good for Portraits. 17 aperature blades , focus to three feet! No info in my books or web. must be very Rare! 610-681-4030,,,, Don
I use it with a Canon DSLR with focus confirmation adaptor. It is really nice. EX bokeh, and with the 1.6 factor, nice for portraits.
