APicture Angle and Focal Length

The D3S can be used with Nikon lenses for 35mm (135) format cameras. If Auto DX crop is on and a 35mm format lens is attached, the picture angle will be the same as a frame of 35mm film (36.0 × 23.9 mm); if a DX lens is attached, the picture angle will automatically be adjusted to 23.5 × 15.6 mm (DX format).

To choose a picture angle 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 35mm format lens is attached, the picture angle 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).
