Condition 97%. Superb, mint- example of this wonderful telephoto lens from Zeiss to fit Contarex SLR cameras. Clean, optics, no fungus or haze. Virtually unmarked barrel. Smooth focus and aperture. Cased, however, the case appears to have come from the factory with the bayonet mount that attaches to the rear of the elns in the wrong half, meaning you can lock the lens into the case, but are then unable to close the case. I've mulled for a while over this and come to the conclusion that it has been put in the wrong way.
