Thanks for the comment. Well, sorry to have raised the lens topic ( because I did it from the beginning). Fact is, I found one for a relatively low price, and in excellent condition. The question is now "is it worth the money", and I try to find the answer, lest I re-sell it. At least I took no financial risk, as I am sure to be able to recover the money.
The portrait was taken on board the train taking me back home a few hours after the transaction, and after a hard working afternoon. I could not wait to try and find an answer to the question.
Expect more pics as I hopefully discover the subtle features making the buy worthwhile. At the same time I try not to post bad pics, let alone brick walls. Photography is not exactly about breaking records.
