Nikon AF DC-Nikkor 105mm f/2D Manuale d'uso

English

Thank you for purchasing a Nikon product. This AF DC-Nikkor 105 mm f/2D lens combines Nikon

defocus image control (DC) with a rounded diaphragm, allowing you to defocus objects in the

foreground or background while making the out-of-focus elements appear more natural. It also

features a rear focusing (RF) system to improve durability and autofocus response; the rear lens

elements slide inside the barrel so that the overall length of the lens does not change during

focusing. A built-in lens hood minimizes fl are in bright sunlight. The lens also supplies distance in-

formation to the camera body for instantaneous 3D matrix metering or 3D multi-sensor balanced

fi ll-fl ash fl ash control. Before using this product, please carefully read both these instructions and

the camera manual so you get the maximum value from your lens now and for years to come.

For Your Safety

CAUTIONS

• Do not disassemble. Touching the internal parts of the camera or lens could result in injury. In the event of

malfunction, the product should be repaired only by a qualiﬁ ed technician. Should the product break

open as the result of a fall or other accident, remove the camera battery and/or disconnect the AC adapter

and then take the product to a Nikon-authorized service center for inspection.

• Turn the camera off immediately in the event of malfunction. Should you notice smoke or an unusual smell com-

ing from the equipment, immediately unplug the AC adapter and remove the camera battery, taking care

to avoid burns. Continued operation could result in ﬁ re or injury. After removing or disconnecting the

power source, take the equipment to a Nikon-authorized service center for inspection.

• Do not use in the presence of fl ammable gas. Operating electronic equipment in the presence of ﬂ ammable gas

could result in explosion or ﬁ re.

• Do not look at the sun through the lens or the camera viewfi nder. Viewing the sun or other bright light source

through the lens or viewﬁ nder could cause permanent visual impairment.

• Keep out of reach of children. Particular care should be taken to prevent infants from putting the batteries or

other small parts into their mouths.

• Observe the following precautions when handling the lens and camera:

- Keep the lens and camera dry. Failure to observe this precaution could result in ﬁ re or electric shock.

- Do not handle the lens or camera with wet hands. Failure to observe this precaution could result in

electric shock.

- Keep the sun well out of the frame when shooting backlit subjects. Sunlight focused into the camera

when the sun is in or close to the frame could cause a ﬁ re.

- If the lens will not be used for an extended period, attach the front and rear lens caps and store the lens

out of direct sunlight. If left in direct sunlight, the lens could focus the sun's rays onto ﬂ ammable objects,

causing ﬁ re.

Notices

■ ■

• Keep the CPU lens contacts clean and be careful not damage the CPU contacts.

• Do not attach the following accessories directly to the lens: PK-1 or PK-11 auto extension rings, K1 or K2

rings, BR-4 auto rings, or BR-2 macro adapter rings (the PK-11A, BR-6, and BR-2A can be used in place of

the PK-11, BR-4, and BR-2, respectively). Failure to observe this precaution will result in damage to the CPU

contacts or other parts of the lens. Other lens accessories may not be compatible with the camera; be sure

to consult the camera manual before use.

• The lens can not be used with the DX-1 viewﬁ nder for Nikon F3AF cameras.

■ ■

Defocus Image Control: Using the DC Ring (Figure A)

To use defocus image control, keep the DC ring lock release button pressed while rotating the

DC ring. To blur background objects, rotate the ring toward "R" (rear). To blur foreground objects,

rotate the ring toward "F". Rotating the ring so that the DC ring index aligns with the f-number

currently selected for aperture throws your subject into sharp relief while artfully blurring objects

in the background or foreground; for a soft-focus eff ect, rotate the ring to a higher number. Always

position the ring before focusing; rotating the DC ring after focusing or while focus is locked will

throw your subject out of focus.

Note that the highest resolution is achieved when the ring index is aligned with the dot between

the two f/2 positions, and that the distance shown by focus distance indicator may diff er from the

actual focus distance when the ring is other positions. When defocus image control is in eff ect,

the focus ring can be rotated past infi nity and the minimum focus distance may, depending on

the position of the DC ring, be greater than 0.9 m (3 ft.).

The eff ects of defocus image control vary with shooting conditions, including the distance be-

tween the subject and the background or foreground. If the eff ects are diffi cult to discern in the

viewfi nder, take a test shot and adjust the ring as necessary.

■ ■

Focus

This lens supports A-M mode selection. To choose the A-M mode, rotate the A-M mode ring while

pressing the A-M mode ring release button. Select A for autofocus and M for manual focus. Choos-

ing an A-M mode that does not match the camera focus mode may damage the camera.

( ):

Figures in parentheses give the exposure compensation for center-weighted metering. Select

"Other screen" for Custom Setting b6 ("Screen comp. " ) when adjusting exposure compensation

for the F6; note that with screens other than B or E, "Other screen" must be selected even when the

value for exposure compensation is 0. Users of the F5 and F4 can adjust exposure compensation

using Custom Setting 18 or the focusing screen exposure compensation dial, respectively; see the

camera manual for details.

Empty cell: Not suited to use with this lens. Note that type M screens can however be used for photomicrog-

raphy and macro photography at magniﬁ cations of 1 : 1 or higher.

The Minimum Aperture Lock Lever (Figure B)

Lock aperture at f/16 when shooting in programmed auto or shutter-priority auto mode.

Rotate the aperture ring to the minimum aperture setting (f/16).

Slide the lock lever toward the aperture ring so that the white dot on the lock lever aligns

with the orange dot.

To release the lock, slide the lever in the opposite direction.

a small amount of ethanol or lens cleaner to a soft, clean cotton cloth or lens-cleaning tissue and clean

from the center outwards using a circular motion, taking care not to leave smears or touch the glass with

your ﬁ ngers.

• Never use organic solvents such as paint thinner or benzene to clean the lens.

(+0.5)

• The lens hood or an NC ﬁ lter can be used to protect the front lens element.

• Attach the front and rear caps when the lens is not in use.

(+0.5)

(+1.0)

• Keep the lens dry. Rusting of the internal mechanism can cause irreparable damage.

• If the lens will not be used for an extended period, store it in a cool, dry location to prevent mold and rust.

Do not store in direct sunlight or with naphtha or camphor moth balls.

• Leaving the lens in extremely hot locations could damage or warp parts made from reinforced plastic.
