Field
The focusing
ring is closest
to the camera
body.
It
has a
knurled rubber
grip
and
engraved
distance
scales
in feet
(orange)
and
metres
(white).
Focus
the
lens by
rotating the
focusing
ring until
you
obtain a
sharp
image of the
subject
in the
viewfinder.
The distance
between
the subject
and the
film
plane
is read
off the
focusing ring's
distance scale
opposite
the central
lens index.
Objects
closer or
further away
than the
selected
distance
will be
sharp, within
certain
limits.
The
limits of this
field of sharp
focus,
i.e. depth
of
field,
vary with the aperture.
The depth of
field available
at any
given
f/stop can
be read off
the depth-of-field
scale on both
sides
of
the central
index.
As an example,
the
rings in
the
illustration
indicate how
to read the
depth of
field scale
at an aperture
of/l
1.
Depth-of-Field
Preview
Depth-of-field
can
be visually
checked
on the

The diaphragm
can
be stopped
down
to the
preset
aperture
from
its normally
wide open
position
simply
by
pushing
the depth-
of-field
preview
lever
downwards
until
it locks.
To reopen the
diaphragm,
depress the
lower
part
of the lever.
