Subject: [Leica] 90mm M Lenses: Which is Most Resistant to Flare & Reflection?

Hello John,
I've used the Summicron 2/90mm (built in Canada 1964)quite a lot without 
any problems except the weight of the lens. A wonderful piece of gear 
but just too heavy, the later version, so I've read , is a lot lighter.

The Elmar-C 4/90mm for the CL is nice and light, a good performer but f4 
is not exactly fast, I've compared this lens with it's Minolta 
counterpart for the CLE and there's no recognisable difference(to me).
These 2 are apparently not supposed to focus as accurately as pure "M" 
lenses when attached to a Leica M camera.
