14 Ch J E G F S IT Ck Depth of Field 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. Minimum Aperture Lock (Fig. 3) For programmed auto or shutter-priority auto exposure 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) 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. Recommended Focusing Screens Various interchangeable focusing screens are available for certain Nikon SLR cameras to suit any picture-taking situation. The ones recommended for use with this lens are: Excellent focusing Acceptable focusing Slight vignetting or moiré patterns appear in the viewfinder, but not on the film. Not available. ( ) Indicates degree of exposure compensation needed (Center-Weighted metering 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. When using the B, B2, E, E2 and K2 focusing screens in cameras other than those listed above, refer to the columns for the B, E and K screens.

15 Ch J E G F S IT Ck Taking Flash Pictures with Cameras having Built-in flash All Nikon cameras having built-in flash are usable and no vignetting occurs. Using a Tripod (Fig. 4) This lens is equipped with a detachable rotating tripod collar. When using a tripod, attach it to the lens'

tripod collar instead of the camera. To attach the tripod collar to the lens, follow these steps:

1 Loosen the tripod collar lock screw

1 slightly.

2 Insert the lens by aligning the tripod collar alignment index on the lens with the mark on the tripod collar.

2 3 Turn the lens to an appropriate position index

3 (three indexes are provided every 90°) on the tripod collar by aligning the tripod collar alignment index on the lens, then tighten the screw. (If the screw is not tight, the lens may accidentally come off the tripod collar.) When holding your camera by its handgrip and rotating the camera in its tripod collar, your hand may bump into the tripod, depending on the tripod in use. Lens Hood Pull out the lens hood by rotating it slowly until the click-stop position is released and the hood moves smoothly. Then, turn it counterclockwise (as viewed from the front) to secure it in the extended position. Because the lens hood is not detachable, slide it back to its click-stop position when not in use. Never lift the lens by its hood. This may cause the lens to drop, due to its own weight, and become damaged, if it hits something hard.

16 Ch J E G F S IT Ck Lens Care ?Clean the 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 or touch other parts. ?Never use thinner or benzene to clean the lens as this might damage the lens, result in a fire, or cause health problems. ?To protect the front lens element, an NC filter is recommended at all times. A lens hood also helps protect the front of the lens. ?When storing the lens in the lens case, attach both front and rear caps. ?When the lens will not be used for a long time, store it in a cool, dry place to prevent mold. Also store the lens away from direct sunlight or chemicals such as camphor or naphthalene. ?Do not get water on the lens or drop it in water as this will cause it to rust and malfunction. ?Reinforced plastic is used for some parts of the lens. To avoid damage, never leave the lens in an excessively hot place. ?Never use an air blower to clean the inside rear portion of the lens. Because the diaphragm blades are exposed, they may be damaged by a strong burst of air. Also be sure to attach the rear lens cap LF-1 when the lens is not in use to protect the lens and diaphragm blades from foreign matter and fingerprints.
