These finders
attach
to the Auto Meter
lV F
and
allow
it
to
make reflected-light measurements.
With
the
Viewfinder
5'
,
the
angle of acceptance
is
5'
;
with
the
Viewfinder 10' ll,
the
angle
of acceptance
is 10" .
The meter
can thus be used
to
accurately spot-measure
exposure
for
parts
of a subject or
scene, or
within
the
approximate angle of
view
of
certain telephoto
lenses.
40' ref lected-light
attach
ment
With
an approximately
40"
angle of acceptance,
this
attachment
permits
taking
reflected-light measurements which
correspond
to the field
of
view of most normal
lenses.
Flat Diffuser
With this
diffuser
attached, the
Auto Meter lV F
can be used
to
measure
exposure
for flat subjects, illuminance
value
of
light, lighting ratio
between
light sources.
Mini Receptor
This
small
remote receptor
plugs
into the
head
of the
Auto
Meter
lV F
to
provide
12mm-diameter measurement
of
incident
light in
otherwise
inaccessible
positions.
lt is
partic-
ularly useful
for
close- ups and
photomacrography.
