Dioptric Adjustment
Lens
S
Dioptric adjustment lenses can
be
attached by inserting them from above into
the grooves
in
the
viewfinder eyepiece
to
compensate for
the
individual eyesight. With
them,
near-sighted or far-sighted persons can
perform photography
without
glasses.
The built-
in
eyepiece lens of
the
AT-1
has
-1
diopter. The following 10 kinds of
dioptric adjustment lenses are optional acces-
sories: +3, +2, +1.5, +1, +0.5, 0,
-0
.
5,
-2,
-3
and
-4
(diopters).
One way of selecting
the
correct dioptric
adjustment lens for you is
to
select
the
one
that
is
the
closest
to
your glasses
in
regard
to
number of diopters. But,
we
propose
that,
to
select
the
most appropriate dioptric ad-
justment
lens,
you
actually look through
the
viewfinder after placing it over the eye-
piece.
Because
the
camera itself has
-1
dioptllr,
the diopters of the lenses are recorded
as
the
real power when attached
to
the
camera, thus
reflecting
the
power of
the
camera's viewfin-
der.
