[Leica] Some technical speculations re: rangefinder

[Frank.Dernie at btinternet.com (Frank Dernie)]

I am interested in what Leica do for the new M10, but not very!
The existing rangefinder, the knowledge of tolerance sensitivity and how to 
calibrate it is well known by Leica. It is basically a variation on the M2 
rangefinder which they have made for decades. All the design work and 
tooling was amortized years ago.

A new optical viewfinder on the type being speculated upon, using the type 
of framelines used on the titanium limited edition may well be a feasible 
development, though getting the chosen frame to change size may not be 
feasible since the actual change in size is lens dependant as well as 
distance dependant.

Making a variable magnification finder which retains sufficient accuracy for 
the rangefinder to work adequately sounds -very- expensive to me...

It is actually very unlikely that the M10 will have any feature which will 
make it a must buy for me personally, though I wait for Leica to surprise me!
