Dear Dr Ted, if I may contribute?
Your answer for your content style is that it doesn't matter.
Its presence dates back to the initial M8 design. It didn't prove to be as
accurate as was originally planned though and hence wasn't used for every
function originally planned. The function is used for TTL flash though.
Keep in mind that Leica Camera needed to ensure compatibility with lenses
from 1954 in a digital system.


Cheers
Geoff
