Refer to “Notes on using wide or super-wide angle AF Nikkor lenses” (p. 66).

Reproduction Ratio and Shooting Distance

Normal focusing extends from infinity to 0.28m (approx. 0.9 ft). A maximum

reproduction ratio of approx. 1:8.9 is obtained at the 17mm setting, while a

reproduction ratio of 1:4.6 is possible at 35mm.

Focusing, Zooming and Depth of Field

(Refer to Quick reference charts 1and 2 on page 73.)

In the M/A (autofocus with manual override) mode, first turn the zoom ring until

the desired composition is framed in the viewfindr before autofocusing. In the M

(manual focus) mode, focusing is possible at any focal length, but the longer the

focal length, the larger the image and the shallower the depth of field, making

focusing easier. If your camera has a depth of field preview (stop-down) button

or lever, depth of field can be observed while looking through the camera

viewfinder.

It is possible to determine depth of field by using the scale provided on page 73.

To Use the Depth-of-Field Scale:

1 Cut out the scales along the lines indicated.

2 Place scale 2 over scale 1 so the top edge of scale 2 is aligned with

the focal length in use and the distance is aligned with the central

indicator line of scale 1.

3 Read the scale 2 numbers that correspond to the aperture in use. For

example, if the lens is prefocused at 1m with the focal length at 28mm and

the aperture at f/22, the depth of field will be approx. 0.6m to infinity.

Minimum Aperture Lock (Fig. 2)

For programmed auto or shutter-priority auto exposure shooting, use the

minimum aperture lock lever to lock the lens aperture at f/22.

1 Set the lens to its minimum aperture (f/22) by aligning it with the aperture

index.

2 Slide the lock lever toward the aperture ring, so the two orange dots are

aligned.

To release the lock, slide the lever in the opposite direction.
