Detailed Operation Depth-of-Field Preview/Film Plane Indicator • Depth-of-field preview Depress the depth-of-field preview button to confirm the depth of field through the viewfinder. • Pressing the depth-of-field button stops the lens down to the aperture controlled in Programmed Auto or Shutter-Priority Auto exposure mode, and down to the aperture selected in Aperture-Priority Auto or Manual exposure mode. By looking through the viewfinder, the approximate depth of field (x 164) with the given aperture can be confirmed. • Modeling flash is also fired with optional Speedlight SB-800 and SB-600 (x 151). To cancel modeling flash, turn the Speedlight off or select "Off" in the Custom Setting "e4: Modeling flash" (x 105). • Exposure is locked (x 72) simultaneously before stopping the lens down with CPU lens. Correct exposure will be obtained by releasing the shutter with the depth-of-field button pressed. • Film plane indicator The film plane indicator shows the position of the film plane inside the camera body. • The film plane indicator shows the standard line of the shooting distance and indicates the position of the film plane inside the camera body. Use this indicator when measuring actual camera-to-subject distance, e.g. in close-up photography. • The exact distance from the lens mounting flange to the film plane is 46.5mm. 83
