Calculating Picture Angle
The
size
of
the
area exposed
by
a
35
mm
camera
is
36 x 24
mm.
The size
of
the
area exposed
by
the
D5000, in contrast,
is
23.6 x 15.8
mm,
meaning
that
the
picture
angle
of
a
35mm
camera
is
approximately
1.5
times
that
of
the
D5000. The
approximate
focal
length
of
lenses
for
the
D5000 in
35
mm
format
can be calculated by
multiplying
the
focal
length
of
the
lens
by
about
1.5.
