Re: [Leica] M6 Wide Angle Body = reduced vf magnification?

[John Collier <jbcollier@home.com>]

My 21mm f3.4 SA (now gone, aargh, BD you were right) brings (gulp, I mean
brought) up the 50mm framelines. It would not be that difficult to remove
the lens mounting flange and solder an suitable extension on. The low heat
involved would not damage the mount. Sigh ..... not that I will ever get to
do it!
