I'm aware that some Summicrons and Summitars are, but I seem to remember some years ago being told that the 2.8 Summaron had "rare earth elements" in it and was also "hot".
It interests me because I would have thought that these "rare earth elements" would have gone into the faster, more expensive lenses of the day i.e. the 35mm Summicron and Summilux, rather than the slower Summaron which at the time was considered more a lens for amateurs than working pros.
