I had been looking for the 50-135/3.5 AIS for some time, after I noticed your shots. Then a beautiful copy at a nice price was offered on Ebay - but, alas, for CONUS sale only. I had to ask an Icelandic friend, living in the States, to buy it and send it to Iceland. It's a great and underrated lens, just like its sister, the 25-50mm/4. Both are excellent.
Glad you were able to find a good one and that you have a friend in the US.
The true sister to the 50-135/3.5 is the 28-50/3.5, another great zoom. The only thing I don't like about it is that it doesn't focus close enough on the wide end.
