I have this lens which I don't need anymore and therefore want to sell - probably on e-Bay. There are lots of the 85mm 1:1,8D to compare with but almost none without the "D". And I have'nt found any description of it. Can anybody tell me something about my lens and possibly how much less than the "D" it would sell for? the 1,8D seems to sell in Europe (e-Bay Germany) for at least 300 euros (400 USD).
