[Leica] Why a digital M

[doubs43 at cox.net (Walker Smith)]

the aluminum barreled lenses
that Nikon sold in the sixties are just plain loose and sloppy now.
Even my Summar from the 1930's is still useable today in the same
conditions it was good for in the thirties.
An excellent point. Quality costs. There's simply no getting around it. I 
own a couple of Leica lens (35mm & 50mm Elmars) that pre-date the 
1933 and up serial number range. They are both well-used and still as tight 
and smooth as one could wish for. That sort of quality comes at a price.
