I see no optical flaws or oil on the blades, which operate as smoothly as they should. Lens body is pristine with the unfortunate exception of a scuff on the sliding lens hood. Similarly the box is in excellent condition barring a couple of puncture marks (seelisting photo seven).

Sample photos were taken with the lens wide open at full zoom, mounted on a Panasonic DMC-G2 with an MFT adapter. 

I only ship to the continental USA - message me for an exception.

Please contact me before leaving feedback if you have any issues, and I will do my best to resolve. I don't leave feedback until I receive it, I want to be sure that I have satisfied buyers! I'm a buyer too, and I try to treat all my customers in the manner in which I hope to be treated myself.
