Nikon f/2.8D instruction manual Aperture, Focusing

Aperture

This lens operates via a preset aperture method. With this method, you must first set the aperture value via the aperture ring. Then, just prior to shooting, you must stop down the lens to the preset aperture using the aperture stop-down button. With this lens, the maximum aperture can be switched to a selected aperture via mechanical push-button operation. The selected aperture is then held until the button is pushed again. Note that even at maximum aperture, the preset aperture value is displayed on the camera body.

•Camera’s in-focus indicator • does not appear properly in the viewfinder when manual focus with electronic rangefinder is performed while shifting or tilting. Focus using the focusing

screen’s clear matte field. However, when shifting or tilting is not performed, focus can be confirmed using the in-focus indicator •.

•When you shift or tilt after focus is achieved, refocus using the focusing screen’s clear matte field.

•To confirm the depth of field at set aperture, refer to the depth of field scale on the lens barrel or see “Depth of Field and Other Data for Shooting” on pages 84-85. However, when shooting at close distance, correct depth of field cannot be attained from the depth of field scale.

•When the lens is tilted, neither the depth of field scale nor the distance scale can be used. (Both scales can be used when the lens is shifted only.)

•The aperture value displayed in the LCD panel or viewfinder of the camera may differ from the aperture value set with the lens’ aperture ring when the focusing ring is rotated. In this case, the aperture value displayed in the LCD panel or viewfinder is the effective aperture.
