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.
A 30.0 × 20.0 mm area at the center of the image
sensor is used to record photographs. To calculate
the approximate focal length of the lens in 35mm
format, multiply by 1.2. 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.
