The shuffer
speed selector
ring is
the ring located
closest to the
front
of the lens. The
desired shutter
speed
is
set opposite the lens index.
The white
scale shows the shutter
speeds, and the
orange scale the exposure values
(EV).
The
aperture ring is located
behind the shutter
speed
ring. The
desired lens aperture is
also set
opposite the
lens index.
The
combination
of aperture and shutter speed set
opposite the
lens index,
determines the exposure.
Every
combination
of shutter speed/aperture
has
an equivalent exposure value
(EV)
which
you can
read
or set against the orange
EV index
on the side
of the
lens.
Exposure values can also be determined
by using
an
exposure
meter having an
EV
scale.

Lens
and Shutter
Functions
If
you want
to change either the shutter speed
or
aperture without changing the EV
(Exposure
Value),
you can
interlock
the shutter speed and
aperture setting
rings.
This is
carried out by de-
pressing
the
interlock
button on the
right
of the
aperture
scale, then turning the
interlocked
rings
to
the desired aperture and speed
combination.
When interlocked
the
rings move
together,
increasing
or decreasing
the aperture and shutter
speed while maintaining
the
EV for
correct ex-
posure.
The focusing ring is
the wide ring with
a
knurled
rubber
grip, set closest to the
camera body.
The
distance scales appear
on this
ring. The lens is
focused
by
rotating
the focusing ring
until the
measured
or estimated distance
between the sub-
ject
and
the
film plane
appears
opposite the
lens
index. The
distance is
shown
in
white for metres,
and in orange for inches/feet
.
Objects closer or further
away than the selected
distance
will appear sharp,
within certain
limits.
The range
of sharp focus, i.e.
depth-of-field varies
with the
aperture.
The
depth-of-field
available at any given
aperture
setting can be read
off the depth-of-field scale on
both sides
of the central
index.
The
setting
in
the
illustration indicates
how
to
read
the depth-
of-field scale at an aperture
of
flll, i.e.
approxi-
mately
from 0.65 m
(2.3
ft.) to l.5m
(5
ft.).
