Luis

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.)
