ACalculating Angle of View
The D4 can be used with Nikon lenses for 35 mm (135) format cameras.
If Auto DX crop is on (085) 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(2 4 × 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 selecti ng 1.2× (30×20), to expose a smaller area, or the aspect
ratio could be changed by selecting 5: 4 (30 ×24).
