[. . . ] Also, keep this manual handy for future reference. Autofocus operation is possible with Nikon autofocus cameras (except the F3AF); manual focus possible with all Nikon SLRs. Thanks to its internal focusing (IF) system, there is no change in the overall length of the lens from infinity to its closest focusing distance of 0. [. . . ] Set the lens to its minimum aperture (f/22) by aligning it with the aperture index. Slide the lock lever toward the aperture ring, so the two orange dots are aligned.

No reproduction in any form of this manual, in whole or in part (except for brief quotation in critical articles or reviews), may be made without written authorization from NIKON CORPORATION. For cameras with TTL metering, there is no need to adjust the aperture. likewise , for TTL auto flash photography with Nikon Speedlights , no adjustment is required. However, when the flash-to-subject distance approaches either the near or far limit of the automatic shooting range, the aperture may need to be adjusted slightly. When using a separate exposure meter or taking photographs in the non-TTL flash mode, select the appropriate aperture index according to the focal length setting in the following way: The aperture index (line) is used for the 24mm focal length setting and the dot for the 85mm setting. Click stops are provided at the aperture index (line) for each aperture setting. For zoom settings between 24 and 85mm, align the aperture ring between the two indexes to obtain the best overall exposure. Taking flash pictures with cameras having built-in flash Check the focal length and shooting distance before taking flash pictures to prevent vignetting. Attaching the hood Align the lens hood attachment index ( ) on the hood with the lens hood mounting index on the lens, and turn the hood counterclockwise (as viewed from the camera side) until it click stops. Make sure that the lens hood mounting index aligns with the lens hood setting index ( ). If the lens hood is not correctly attached, vignetting can occur.
