378nA Calculating Angle of ViewThe D800 can be used with Nikon lenses for 35mm (135) format cameras.If Auto DX crop is on (0 79) and a 35mm format lens is attached, theangle of view will be the same as a frame of 35mm film (35.9 × 24.0 mm);if a DX lens is attached, the angle of view will automatically be adjustedto 23.4 × 15.6 mm (DX format).To choose an angle of view different from that of the current lens, turnAuto 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, theangle of view could be reduced by 1.5 × by selecting DX (24×16) or by1.2 × by selecting 1.2× (30×20), to expose a smaller area, or the aspectratio could be changed by selecting 5 : 4 (30×24).LensFX (36×24) picture size (35.9 × 24.0 mm,equivalent to 35mm format camera)Picture diagonalDX (24×16) picture size(23.4 × 15.6 mm, equivalent to DXformat camera)5 : 4 (30×24) picture size(30.0 × 24.0 mm)Angle of view (FX (36×24);35mm format)Angle of view (DX (24×16); DX format)Angle of view (5 : 4 (30×24))1.2× (30×20) picture size(30.0 × 19.9 mm)Angle of view (1.2× (30×20))
