'I
Calculating
Picture
Angle
The 0700 can be used
with
Nikon lenses
for
35mm (135) format cameras.
If
Auto
OX
crop
is
on (the default setting) and a 35mm
format
lens
is
attached,
the
picture angle will be
the
same
as
a frame
of
35mm film
(36.0
x 23.9 mm);
if
a
OX
lens
is
attached,
the
picture angle will
automatically be adjusted
to
23.5 x 15.6
mm
(OX
format).
To
choose a picture angle differentfrom
that
of
the
current lens,
turn
Auto
OX
crop
off
and select
FX
format
(36 x 24) or
OX
format
(24 x 16).
If
a
35
mm
format lens
is
attached,
the
picture angle could be reduced by
1.5
x by selecting
OX
format
(24 x 16), exposing a smaller area.

'---------------------------
The
OX
format
(24 x 16) picture angle
is
about
1.5
times smaller than
the
35mm format picture angle.
To
calculate
the
focal length
of
lenses in
35mm format when
OX
format
(24 x 16)
is
selected,
multiply
the
focal
length
of
the
lens by
about
1.5
(for example,
the
effective focal length
of
a
50mm lens in 35mm format
would
be
75
mm
when
OX
format
(24 x 16)
I.-I
is
selected).
