Angle
and
Focal
Length
The
size
of
the
area
exposed by a 35-mm camera
is
36x24mm.
The
size
of
the
area
exposed by the
D40,
in
contrast,
is
23.7x
15.6,
meaning that the
picture angle
of
a 35-mm
camera
is
approxi-
mately
1.5
times that
of
the 040.
The
approxi-
mate focal length
of
lenses
for the
D40
in
35-mm
format
can
be calculated by multiplying the focal
length
of
the
lens
by about
1.5.
