[Leica] an M9 question...

[henningw at archiphoto.com (Henning Wulff)]

In a simplified, but reasonably accurate way:

Longer tube = narrower angle of view.
Longer tube refers to the distance of eyepiece to front glass of the 
viewfinder, which is longer for the M8/9 than M film bodies. This can 
be compensated for by complicating the optical construction of the 
finder, but that really opens a can of worms, and the internet forums 
would be alight with outrage.

So, short of a complete redesign of the view/rangefinder I think 
Leica did the right thing. Personally, I would like to see Leica put 
in a range/viewfinder like the ZM has, and now they could do that 
since there is no rewind crank, but again a large percentage of the 
'conservatives' among Leica owners would scream.

Also, my 135 Elmarit would no longer work, and all those hordes 
currently doing major work with SOOKY-M's would be out of luck.
