Images are recorded in FX
format using the full area of the
image sensor (36.0 × 23.9 mm),
producing a picture angle
equivalent to a Nikkor lens on a
35mm format camera. The
edges of pictures taken with DX
format lenses will be blacked
out.
An area at the center of the
image sensor 23.5 × 15.6 mm is
used to record pictures in DX
format. To calculate the
approximate focal length of the
lens in 35mm format, multiply
by 1.5.
Pictures are recorded with an
aspect ratio of 5 : 4
(30.0 × 23.9 mm). The edges of
pictures taken with DX format
lenses will be blacked out.
