I have on several occasions posted here a list of 
the effective rangefinder base for a number of RF 
camera systems.  In minature-format, the Kodak 
Ektra takes the cake, with a huge effective 
base.  The Leica thread-mount cameras have a 
longer effective base than do the M's which makes 
them essentially more accurate.  The Prewar 
Contax II and III and the Postwar Jena Contax and 
Kiev RF clones are significantly better, though, 
than the later LTM cameras and have a better VF to boot.

(About fifteen years back, I started writing a 
history of the Leitz works and the Leica 
camera.  I got up to the introduction of the M 
series and it got set aside for other 
projects.  This table comes from this 
work.  Someday I ought to go back and finish 
it:  the text is on my computer though, 
admittedly, the last significant writing was two 
computers back.  I always copy the important 
stuff such as my writings and Wolfenstein 3D when I buy a new computer.)
