Hi,
if interested in lenses weights, I have measured and collected some, they
are on one of my web pages
http://fractales.inria.fr/~louchet/perso/masses.html
(written in French and partly translated into English)
The lightest L39 lens I know is the Russian ORION-15, 6/28mm at 61 grams.
Probably not the best 28 around, or the fastest :-) but very acceptable
pics. With the L39 to M adapter (12 grams) it weighs 73 grams (without
cap). Ultra-slim, very handy on a pre-M leica or Zorki in the pocket.
Canon Serenars are on the heavy side (e.g. 577 grams for the 2/85 without
caps, hood or M adapter). I would bet that the lightest genuine leica lens
is an old, L39, low aperture 28 or 35mm.
I don't know the weight of the Summicron-M 2/40 but its very close
equivalent M-Rokkor 2/40 weighs 104 grams, so the R3a should weigh roughly
about 24 grams more than the CL and 44 grams more than the CLE. About the
weight of two 36-exp. film cartridges.

Oops
My 40mm Summicron weighs 4 oz on my kitchen scale.
Rubber hood .5 oz.
Is there a lighter Leica lens? It's sure lighter than Karen's silver
collapsible Elmar 50 current.
