[Leica] The Polarizer Problem

["Bryan Willman" <bryanwi@seanet.com>]

Tom, other folks who make things,
please hear my plea...

What to do about polarizers on M6s?

The Universal swing-swap thingy that
Leica makes doesn't actually fit the 
lenses I own, so it doesn't help.

So, what does one do?  (What
have you Luggers actually done?)

A.    Mark the filter very carefully.
Hold it up and orient it.  Notice what
mark is up.  Mount it on the camera
and arrange for that mark to be up.

Pro:    Works with any polarizer.
Con:    Hard to execute.

B.    Make a two filter polarizer.
One is mounted to the front of
the lens.  The other is mounted,
via some fixture, in front of
the viewfinder.  They are linked
via gears.  As you turn one, the
other moves.  They are aligned.

Pro:    Could be made big enough.
            Would be fast in action.
Con:    No such device exists.
            Hard to mount.

C.    Some other easy/clever thing...
