I decided to take a quick look around and see which of my Leica lenses aren't made in Germany (i.e. Canada - horror!!! :-) ):
Summicron R 90mm
Summicron M 35mm
Apo-Telyt 180mm f/3.4
While the Tele-Elmarit might not be the absolute best of the 90mm Leica lenses for some aspects, it is a great carry around and landscape lens.
The others are among my favorites.
There is definitely nothing "magical" about "Made in Germany".
BTW. I tend to prefer the look of Zeiss glass to Leica, though more recent Leica lenses are arguably technically better. Leicaflex SL & SL2 bodies are a strong argument for using Leica leses, even if they are less endowed with that 3d look.
