Zeiss Planar 100/2 lens. Originally in C/Y mount, it has been converted to m42 mount, but it comes with sony/minolta alpha mount, with focus confirmation chip. Lens looks old, but is in good condition. Body is clean, no dents or scratches. Bezel has couple tiny nicks on top part, visible on the picture. Glass is free of mold, haze or fungus. Due to the age of the lens, there are some visible dust specks inside. Focusing ring is smooth and dumped. Aperture ring works well without any loose and with audible clicks at any aperture change. Lens is really great, very sharp wide open, with great colors, contrast. It really gives the Zeiss "pop", even at smaller apertures. Comes with Contax front cap and Minolta rear cap. I will also include the UV filter and original CY mount, in case someone want to reverse to the original mount. Price for the entire set is $700 net to me, including shipping by EMS Korea (usual transit time is 3-6 days).
