I have the above lens up for sale. It is in excellent shape, very minor marks of use on the barrel; the glass is perfect; shutter, diaphragm and distance mecanisms are perfect. It comes with a Hoya skylight filter, a front cap but no rear cap and a square leathercase which however is quite marked by use.
It does not have long time exposure feature (shutter speeds go to 8 seconds but there is no T position) - that only comes with other Zenzanon lenses.
My price would be 80€ + postage which is 8€ in Europe, 12 € elsewhere.
