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.

MOUNTING THE LENS A To mount, position the lens in the camera's bayonet mount, lining up the aperture index on the lens with the lens mounting index on the camera. Twist the camera body clockwise until it clicks into place.

To remove, press the lens release button on the camera and turn the camera body counterclockwise. For details, refer to the camera's instruction manual. Note: When the lens is used with the Nikon F-401/N4004*, the camera meter coupling function does not operate and the exposure indicator LEDs do not appear. *The Nikon N4004 is sold exclusively in the U.S.A.

FOCUSING Turn the focusing ring until the image in the viewfinder appears sharp and crisp. The effective focal length may vary in extreme heat or cold. To compensate for this, turn the lens focusing ring slightly beyond the °° (infinity) position.

Preset Focusing B When you want to refocus rapidly to a specific object distance, preset the focused distance. 1. Loosen the preset-focus ring lock screw and turn the ring in either direction until it clicks. 2. Turn the focusing ring to set the desired distance. 3. Tighten the preset-focus ring lock screw.

DEPTH OF FIELD Depth of field can be checked with the color-coded depth-of-field indicators engraved on the lens barrel.

If your camera has a depth-of-field preview function, it is possible to check the depth of field in the viewfinder. (For details, see camera instruction manual.) Depth of field can also be checked by referring to the table on page 31.

INFRARED PHOTOGRAPHY In infrared photography, it is necessary to make the following adjustments to the focused distance.

1. Focus subject. 2. Reset the focusing ring to align the focused distance with the infrared focusing index. 4. Attach the appropriate filter, such as R60, etc., and take the shot.

USING FILTERS Always use a filter with the lens. The slip-in glass filter holder comes mounted with a

Nikon L37C filter. A slip-in gelatine filter holder is also supplied with the lens.

Replacing Glass Filters

1. Press down on the glass filter holder knob, and turn counterclockwise until the white line on the knob is at a right angle to the axis of the lens.

2. Pull the holder out. 3. Unscrew the mounted filter and replace with the filter you want to use. 4. Put the holder back, push down on the knob, and turn clockwise to lock.

Using Gelatine Filter

1. Cut the gelatine filter into a circle of approx. 40mm (1.6 in.) in diameter.

2. Open the gelatine filter holder plate by pushing on the latch and lifting up. 3. Insert the gelatine filter into the holder and close the plate. Make sure the filter is unscratched and free from dust and take care that it stays flat. 4. Remove the glass filter holder from the lens and insert the gelatine filter holder.

USING LENS HOODS When shooting in bright sunlight, use the lens hoods to prevent stray light from entering your lens.

To Use Built-in Lens Hood

1. Turn the hood clockwise and pull out as far as it goes.

2. Secure in place by continuing to turn until it locks. T o Attach Extention Lens H o o d HE-4 1. Loosen the lock screw on the HE-4. 2. Slip the HE-4 onto the front of the built-in hood. 3. Tighten the locking screw.

F RECOMMENDED FOCUSING SCREENS Various interchangeable focusing screens are available for F3- and F2-series cameras to suit any type of lens or picture-taking situation. Those which are recommended for use with your lens are listed below. For screens used with Nikon cameras other than F3and F2-series cameras (e.g., Nikon FA, FE2, FM2 and FE), refer to the column for F3series cameras. 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 sheet. ~~~ — — - . ^ ^ Screen Camera '—-—^__

• Although you should always keep the lens surfaces clean, rough cleaning must be avoided. Wipe with a soft, clean cotton cloth moistened with alcohol tq remove grease or fingerprints 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. • Take care in cleaning the rear part of the lens with a spray-gun type blower, because its strong stream of air may damage the lens diaphragm blades. To avoid damage, set the lens at full aperture and use the blower far enough away. • Always protect the lens surface from dirt or damage. The lens hood also helps tq protect the lens. • Keep the lens cap in place whenever the lens is not in use.

ABOUT THE NIKKOR F n QFRTF5

Correction of chromatic aberration in camera lenses has been limited, for the most part, to the use of techniques which bring

* w o w a v e l e n g t n s of light, normally blue and red, to a common focus. Although known as "achromatic," lenses employing these designs exhibit a certain amount of undersirable residual dispersion (called the "secondary spectrum") which limits image contrast and sharpness, particularly at full aperture. Telephoto lenses are most prone to the ill effects of chromatic aberration, since secondary spectrum increases with focal length. The Nikkor ED series consists of telephoto and super-telephoto lenses fitted with elements made of a Nippon Kogaku-deveioped special optical glass called "Extra-low Dispersion" (ED) glass. Although the optical characteristics of this new glass are similar to those of calcium-fluortte crystal, ED glass possesses a more constant refractive index over a wide range of temperatures and will, therefore, cause less of a focus shift. Also, ED glass is much harder and more resistant to scratches, enabling its use for front and rear lens elements to obtain optimum correction of chromatic aberration over the widest possible wavelength range. Some lenses within the ED series have been so fully corrected that image sharpness extends uniformly to the infrared region; for these lenses, corrective refocusing for infrared exposure is unnecessary. The remaining lenses, such as this Nikkor 300mm f/2.8 IF-ED, have been built exceptionally compact due to the use of ED glass elements; for these lenses, however, corrective refocusing for infrared photography is necessary. Regardless of which type, ED-series lenses offer exceptional sharpness and full contrast for the most precise photography under the widest conditions.
