Some types of
the finder
screens exert
on influence
up.:>n
the measuring result
of
the
meter.
To compensa te
the
in
fluence, change the fi
lm
speed

figure
as
shown by
the
numbe
r
printed
in bold
b lock
in
fhe table
Isee
opposite pagel,
depending
upon
the type
of
the lens
being used.
However, for the lenses
of small
max
,
aperture,
where such
adjustment
goes
beyond the
lim
it
of
the
max.
aperture
adjustment, it
must be
made
by
decreasing the exposure determined by meter
as
many steps as
shown
by the
red
numbers in
the table, the
film speed being set
to the max. aperture of the
lens.
For
example, when
using the

and the
finder
screen type H2, the
necessary adju

Then,
provided

change the
shutter
sp~ed
