Thank you for your kind patronage of Nikon.
Before using your new lens, read the following carefully so you
get the most out of your lens now and for years to come.
Important!
* Be careful not to soil or damage the CPU contacts.
* Do not attach the following accessories to the lens--they
might damage the lens' CPU contacts:
Auto Extension Rings PK-1 and PK-11; K1 Ring; Auto Ring
BR-4.
(Use PK-11A instead of PK-11, BR-6 of BR-4)
* This lens cannot be used with AF Finder DX-1, attached to the
Nikon F3AF camera.
* Other accessories may not be suitable for use with certain
cameras. For details, carefully read the camera's instruction
manual.
Focusing/Zooming
With the Nikon autofocus cameras, both autofocus and manual
operation are possible. Also, thanks to an improved exit pupil
diameter, this lens can be used with AF (autofocus) cameras for
focus-assist operation at any aperture setting, even those slower
than f/4.5. For manual focusing, rotate the focus ring until the
viewfinder image appears sharp and crisp. The effective focal
length may vary in extreme heat or cold. To compensate for this,
the lens focusing ring is designed to turn slightly beyond the «e
(infinity) position.
in and out, move the zoom ring straight ahead or back
until the desired composition is framed in the viewfinder. In mat"
ual focus, you can also zoom by holding the focus ring and mov-
ing it straight forward or back. For pinpoint focusing, focus with
the lens in the 300mm zoom position, then change to the
desired focal length.
Focusing Limit Switch
In cases when you want to shoot within a specified distance
range, you can reduce focusing time by setting the focusing limit
switch from FULL position to LIMIT. (There are two focusing limit
Zones; approx. 3m [10 ft.] to infinity for normal shooting, approx.
3m [10 ft.] to M for macro shooting.)
Macro focusing
Normal focusing lets you focus from infinity to 3m (approx. 10
ft), but for macro focusing down to 1.5m (approx. 5 ft) at any
focal length setting, simply continue turning the ring. The orange
"M" and distance scale line indicates macro-mode focusing. At
the closest macro focus distance, the reproduction ratio is 1:3.8
at the 300m focal length setting; 1:15 at 75mm.
Recommended Focusing Screens
Various interchangeable focusing screens are available for Nikon
cameras to suit any type of lens or picture-taking situation.
Those which are recommended for use with your lens are listed.
For the K2, B2, and E2 focusing screens, refer to the columns on
the K, B and E screens, respectively. For details, also refer to the
specific focusing screen's instruction manual.

©= Excellent focusing
O= Acceptable focusing
Slight vignetting or moire phenomenon affects screen
image, but film image shows no traces of this.
@= Acceptable focusing
Split-image rangefinder, microprism or cross-hair area is
dim; focus on the surrounding matte area.
= Exposure measurement is not possible; lens/screen combi-
nation permits focusing operation only.
Blank box means not applicable. Since type M screen can be
used for both macrophotography at a 1:1 magnification ratio and
for photomicrography, it has different applications than other
Screens.
* Screen T and U are not available for use with F2-series cam-
eras.
Variable Aperture
Zooming the lens in from 75mm to 300mm decreases the maxi-
mum aperture approx. 2/3 of an f/stop. For this purpose, the
lens has two aperture indexes: the green index is used for the
75mm focal length setting; the yellow one for 300mm setting. A
Click stop is provided at the green index.

For cameras with TTL metering, you need not worry about
adjusting aperture. However, when using an independent expo-
sure meter, select the appropriate aperture index according to
the focal length setting. For intermediate focal length settings,
align the aperture ring between the two indexes. Refer to dia-
gram 1 for the relationship between focal length and maximum
aperture.

Flash Photography Care
Because lens aperture varies according to focal length setting,
special care is required when performing flash photography.
For TTL automatic flash photography
When the flash-to-subject distance approaches either the near
or far limit of the automatic shooting range, aperture may need
to be adjusted as you zoom in or out.
