I purchased this lens here a few weeks ago. It is a very cool looking piece of glass, but I'm not sure I have the game for this one just quite yet. Lens is in great shape. Aperture clicks nicely at all stops; focus ring seems perfect to me. A little dust, small scratch in coating on front element, and cleaning marks on rear element. Nothing that impacts IQ. Asking $135 shipped/insured; standard PayPal. I will include a C-mount to micro 4/3s adapter (not pictured). It works well with my E-PL1. Please PM me with any questions or offers. The last pic was taken with the lens on the E-PL1, at f/4 iirc on a very overcast day. That image is straight from camera. That vignette is "standard" with this lens on m4/3. Thanks for looking.
