Panasonic/Leica also cheats on the weight spec. They say 985 grams, for the lens without its front cap, without its back cap and without its tripod mount.

 

Even with its caps and without the mount it goes over 1 kg

 

Now you are nit-picky ;-)


However, the upcoming Leica 50-200mm f/2.8-4 should be WAY below 1kg (and after that's a "400mm" lens).
