ACalculating Angle of View
The D4 can be used with Nikon lenses for 35 mm (135) format cameras. If Auto DX crop is on (0 85) and a 35 mm format lens is attached, the angle of view will be the same as a frame of 35 mm film (36.0 × 23.9 mm); if a DX lens is attached, the angle of view will automatically be adjusted to 23.4 × 15.5 mm (DX format).
To choose an angle of view different from that of the current lens, turn Auto DX crop off and select from FX (36×24), 1.2× (30×20),
DX (24×16), and 5 : 4 (30×24). If a 35 mm format lens is attached, the angle of view could be reduced by 1.5 × by selecting DX (24×16) or by
1.2× by selecting 1.2× (30×20), to expose a smaller area, or the aspect ratio could be changed by selecting 5 : 4 (30×24).
