Images are recorded in FX format using the full area
of the image sensor (35.9 × 24.0 mm), producing an
angle of view equivalent to a NIKKOR lens on a
35mm format camera.
A 30.0 × 19.9 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.
An area at the center of the image sensor
23.4 × 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 × 24.0 mm).
