The manual focus confirmation is when all the little dots dissapear and there
is only one dot left when rotating the focus wheel.  Presetting the focus for
street photography won't speed up you photography as when you depress the
shutter release the lens still has to move to the correct position for the
pre-determined focus.  The manual focus is quite accurate, as accurate as the
auto focus.  The problem is for we Leica users the wheel has no machanical
feel and does not focus the lens.
