[. . . ] Within certain limits , howevet , these may appear reasonably and acceptably sharp . The range within which points in front of and behind the point of focus , appear acceptably sharp , is called the depth of field . Depth of field increases as the aperture of the lens is made smaller. Shortenin g the lens focal length or increasing the distance between lens and subject also increases depth of field. These three factors can operate independently or in conjunction . One factor may act to partially cancel the effect by the other. 18 DEPTH·OF ·FIELD PREVIEW BUTTON Nikko, mat :; The Nikkor lens has a"color -coded depth of field scale engraved on the lens barrel just behind the focusing ring. This color code permits easy reading of the ct. epth of field scale for any selected aperture . Each set of colored lines located one on either side of the middl~ line represents a different F-number. The color of the line matches that of the F-number engraved on the aperture ring . For example , when using the 50 mm F(1. 4 lens , with the distance scale set ting at 15 ft and with an Fj 16 openin g (F j 16 is shown in blue), the depth of field indicated by the blue -colored lines on either side of the black index will be between 8 ft and 00 . T~is means that a picture taken at Fj 16 , with the lens focused at 15 ft will show a range of acceptable sharpness between 8 ft and 00 . The sharpest point will be at 15 ft . LL 3 LL Q LL. u: U; c " " C Press the button located on the camera top at the right side of the viewfinder (viewed from behind the camera). and the aperture diaphragm will be closed down to the preselected aperture. This permits viewing the depth -of -field at . . takin g" aperture , or selecting the . . taking" aperture on the basis of depth of -field . Release the button and the diaphragm will instantly reopen . The depth -of -field is read on the color coded depth -of -field scale engraved on the barrel of each Nikkor lens. :i. . . . C LL. 19 SELF·TIMER The sel f ·timer is a devi ce which delays the action of the shutter after the shut · ter release button is depressed.
