can also be
prefocused
using the
distance
scale engraved
in
both feet and meters on the
lens
barrel. Line
up the
bl

indicator
line
on top of
the
lens
opposite the camera-to-subject
distance
as
measured
or estimated.
This technique is useful
for
candid shots of elusive ,subjects when time
does
not permit
through-the-Iens focusing.
The
mark

deck
shows the exact
position of
the film
plane.
This is
an aid when
measuring
the film-to-subject
distance
in close-
ups
and
macrophotography.
