Condition 97%. Superb, mint- example of this wonderful semi-auto lens from Zeiss in M42 screw mount. The semi-auto aperture on these lenses require you to set the aperture on the sprung aperture ring as you would on a preset, then to cock the mechanism by turning it clockwise and allowing it to return; when you fire the shutter on your camera it will activate the pin on the rear of the lens and stip he lens down to the selected aperture. Serviced. Clean optics & barrel. Smooth focus and snappy aperture. Front & rear caps. Fabulous lens.
