For sale is a Revuenon 55mm F1.2 in K-mount. I purchased from another forum few days ago and prior starting to use it on my olympus with an adapter, I have decided that I need to switch to a video camera system, hence the selling of this lens. It comes with original front and back cap, and no exterior scratches, but I have not test it on any camera, the person who sold me the lens said it has no issue but I am not guaranteed on that, focus ring is smooth and appear no scratch/fungus. Price to sell: $350 net + shipping. Item can be shipped from Hong Kong or Canada in few weeks if desired. Return only if differ from description.
