Re: [Leica] Rangefinder Effective Base

["Bill Larsen" <ohlen@sierratel.com>]

I believe that that is the reference to the "notch" in the finder that when
using the 50 mm lens shows the depth of field at f/16 (top mark) and f/5.6
(bottom mark).  I think that this was a "feature" of the late M3s and M2s. It
is used with the split image rangefinder image.  Personally, I have never used
this "feature" as it seemed rather convoluted.

|Hi John,
|
|     And thanks, I checked the site above;  the screw mount Leicas are
|just slightly less than an M3, slightly more than the M2.
|
