Important!

•Be careful not to soil or damage the CPU contacts.

•Do not attach the following accessories to the lens, as they might damage the lens’ CPU contacts:

Auto Extension Ring PK-1, Auto Extension Ring PK-11*, K1 Ring, Auto Ring BR-4**

•This lens cannot be used with AF Finder DX-1 attached to the Nikon

F3AF camera.

*Use PK-11A instead. **Use BR-8 instead.

Using Filters

As standard equipment, four rear-mounting bayonet-type filters (137C, A2, B2 and 056) are supplied with the AF Fisheye-Nikkor 16mm f/2.8 D lens. Because of the optical construction of this lens, it is necessary to keep a filter attached to the lens at all times.

To exchange filter

(1)Rotate the already-attached filter counterclockwise to remove.

(2)To attach the filter, align the dot on the outside rim of the filter and the groove beside the mounting pin on the lens bayonet, then rotate the filter clockwise.

Composing (Illust. B)

Using a fisheye lens requires much more e planning and thought about picture composition than does a conventional lens. The lens not only produces wide-angle distortion but it also exaggerates the relative size of objects to conform to its format: objects near the center are bigger than those at the edges, and they show less optical distortion. The entire field is pushed into the distance and spatial relations are transformed. and with a slight shift of the camera, quite new distortions are created. Be careful not to accidentally include in the picture unwanted ovjects, such as the legs of a tripod or the hands or feet of the photographer.

Forward

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.

Unlike other Nikkor fisheye lenses producing a circular image, the AF Fisheye-Nikkor 16mm f/2.8 D lens fills up the frame with an image. But it still possesses a 180° angle of view (as measured across the diagonal) and gives you the same exciting fisheye effects as regular fisheye lenses. Also, distance information used for 3D Matrix Metering or the 3D Multi- Sensor Balanced Fill-Flash will be transmitted instantly from the lens to the camera body.

Focusing

With the Nikon autofocus cameras, both autofocus and manual operations are possible. To focus manualy, rotate the focus ring until the image in the viewfinder appears sharp and crisp.

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 recommened for use with your lens are listed on page 24.

Exposure compensation is required. Refer to table below:

Film	Filter		Compensation value (Filter factor)
	Type	Designation	Daylight	Tungsten light
B/W and color film	Ultraviolet	L37C	1	1
Color film only	Light Amber	A2	1.2 (1/3)	1.2 (1/3)
Color film only	Light Blue	B2	1.2 (1/3)	1.2 (1/3)
	Light Blue	B2	1.2 (1/3)	1.2 (1/3)
B/W film only	Orenge	O56	3.5 (15/6)	2 (1)

( ) = Exposure compensation in f/stops

Minimum Aperture Lock (Illust. A)

For programmed auto or shutter-priority auto shooting, use the minimum aperture lock lever to lock the lens aparture at f/22.

1.Set the lens to its minimum aperture (f/22).

2.Slide lock lever in the direction of the aperture ring and so the white dot on the lever aligns with the orenge dot.

(See illust.A)

3.To release the lock, slide lever in reverse direction.

Lens Care

•Clean lens surface with a blower brush. To remove dirt and smudges. use a soft, clean cotton cloth or lens tissue moistened with ethanol (alcohol) or lens cleaner. Wipe in a circular motion from center to outer edge, taking care not to leave traces and not to touch the other lens parts.

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.

•Never use thinner or benzine to clean the lens.

•Keep the lens cap in place whenever the lens is not in use.

•If 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.

•Be careful not to get the lens wet or drop it in water. Water on the lens may cause malfunction.

•Reinforced plastic is used on the exterior of the lens unit; to avoid damage, take extra care to never leave the lens in an excessively hot place.
