Sadly, now missing from his Website. V3 was Canadian. I have one. I just checked EBay for a picture of V4 (easy to tell apart as V4 has tabs on the iris ring, V3 does not). That lens clearly states Canada as well. It may be true that some V4 were made in Germany but we can be sure that some were made in Canada. When Leica started to pull out (Got thrown out due to business decisions of Hughes/ Raytheon) of ELC, there was a transition period before the designs were changed and the ASPH and APO lenses versions came out. Some stuff was made in Germany when traditionally they were made in Canada. Frank Filippone > According to some chart I found online, Version 3 was made in Canada, > Version 4 in Germany.
