I do not believe you are asking if the weight of Leica lenses is less
because they use new adhesives.  Ditto the size.  Adhesives weigh basically
nothing ( if only because such minute quantities are used.)
Where are these adhesives supposed to be used?  they always used adhesives 
to 
glue lens elements together, from the very begining, this is common 
practice. 
 I'm sure there are adhesives used to hold rubber gripping surfaces on some 
of the R lenses and also body coverings of all bodys.  According to Karl, 
the 
tour guide at the factory all Leica lenses are made with metal mounts and 
internal workings, no plastic inside the lenses at all.  I realise he does 
not 
actually work on the lenses, but this is the factory line.  I cant remember 
his 
entire last name, but I think it is Karl Heinz Wolker.  I will comment that  
when I was at the factory for the tour in December, it appears that the 
factory 
seems to be gearing up for making lens production as its main production, 
with 
only final camera body assembly, adjustment and inspection in Solms, and the 
majority of camera body production being done in Portugal.  The only camera 
work I saw was in one corner of the facility with the rest setup for lens 
production only.
