[Leica] M6 .56 viewfinder and wide-angle lenses

["Mxsmanic" <mxsmanic@hotmail.com>]

I understand there is now a 0.56 M6 TTL available.  Does this model allow use of
focal lengths below 28mm without an external viewfinder (i.e., with built-in
frame lines), or is the external finder still required for very wide-angle
lenses?  Since I like wide-angle shots with my rangefinder I'm thinking of
putting the 0.56 on my long-term wish list, but I'm curious as to whether it
eliminates the need for an external finder.  I'm not sure that I want to go to
the trouble of an external finder if that is still necessary (if it is, I might
just be satisfied with a 28mm lens on my wish list).
