For non-TTL automatic or manual flash photography
Slight adjustment of aperture is required—using the intermedi-
ate setting between the green and yellow aperture indexes gives
you approximately correct exposures for all focal length settings.
For precisely correct exposures, adjust the aperture according to
diagram 1.
Depth of Field
Unlike most Nikkor lenses, the AF-Nikkor 75-300mm f/4.5-5.6
lens has no depth-of-field indicator engraved on the lens barrel.
It is possible, however, to determine depth 'of field by using the
scale provided on this sheet.
To use depth-of-field scale
1. Cut out the scales along the lines indicated.
2.Place scale B over scale A so the top edge of scale B is
aligned with the focal length in use and the distance is aligned
with the central indicator line on scale A.
3. Read the scale B numbers that correspond to the aperture in
use.
For example, if the lens is prefocused at 10m with the focal
length at 100mm and the aperture at f/32, the depth-of-field
will be from approx. 5m to infinity.
Minimum Aperture Lock
For programmed auto or shutter-priority auto shooting, use the
minimum aperture lock lever to lock the lens aperture at f/32.
1. Set the lens to its minimum aperture (f/32)
2. Slide lock lever in the direction of the aperture ring and so the -
white dot on the lever aligns with the orange dot.
(See illust. A)
3. To release the lock, slide lever in reverse direction.

Lens Care
Although you should always keep the lens surfaces clean,
rough cleaning must be avoided. Wipe with a soft, clean cot-
ton cloth moistened with alcohol to remove grease or finger-
prints from the lens surfaces.
If you use ether in cleaning the lens, a smudge sometimes
appears on the surface of a multi-coated lens. If this happens,
wipe it again with a cotton cloth moistened with alcohol.
e Never use thinner or benzine to clean the lens
e To protect the lens surface from dirt or damage, the use of an
L37C filter is recommended at all times. The lens hood also
helps to protect the lens.
* Keep the lens cap in place whenever the lens is not in use.
e Attach both the front and rear caps when the lens is stored
separately.
e To ensure proper fit of the lens when stored in the leather lens
case, set the lens focus ring to the infinity (ee) and the zoom
ring to the 75mm setting.
e |f you will not use the lens for a long time, protect it from rust
and mold by storing it in a cool, dry place. Also, do not store in
direct sunlight, and keep it away from naphthalene or
camphor.
* Reinforced plastic is used for some parts in the lens unit; to
avoid damage, take extra care to never leave the lens in an
excessively hot place.
