Do not handle the lens or camera with wet hands. Failure to observe this precaution could result in electric shock.![burn hazard]()
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 fire.![burn hazard]()
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 flammable objects, causing fire.

M/A (Autofocus with Manual Override)
To focus using autofocus with manual override (M/A):
- Slide the lens focus-mode switch to M/A.
- Focus.
If desired, autofocus can be over-ridden by rotating the lens focus ring while the shutter-release button is pressed halfway (or, if the camera is equipped with an AF-ON button, while the AF-ON button is pressed). To refocus using autofocus, press the shutterrelease button halfway or press the AF-ON button again.
Depth of Field
The depth-of-field indicators on the lens show the approximate depth of field. If the camera offers depth-of-field preview (stop down), depth of field can also be previewed in the viewfinder. See the depth of field table for more information.
Aperture
Aperture is adjusted using camera controls.
Built-in Flash Units
When using the built-in flash on cameras equipped with a built-in flash unit, shoot at ranges of 0.6 m (2 ft) or more and remove the lens hood to prevent vignetting (shadows created where the end of the lens obscures the built-in flash).
The Lens Hood
The lens hoods protect the lens and block stray light that would otherwise cause flare or ghosting.
Attaching the hood
Align the lens hood mounting mark (
) with the lens hood alignment mark (
) and then rotate the hood (
) until the mark is aligned with the lens hood lock mark (—
).
When attaching or removing the hood, hold it near the symbol on its base and avoid gripping it too tightly. Vignetting may occur if the hood is not correctly attached.
The hood can be reversed and mounted on the lens when not in use.
Focusing Screens
The following cameras support a variety of focusing screens for use in different situations.
| Camera | Screen | ||||||||||||
| A | B | C | E | EC-B EC-E | G1 | G2 | G3 | G4 | J | L | M | U | |
| F6 |  | |  | | | | | | | | | | |
| F5+ DP-30 | | | | | | | | | |||||
| F5+ DA-30 | | | | | (+0.5) | | | | |||||
: Recommended
: Vignetting visible in viewfinder (photographs are not aff ected).
: Not compatible with 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. Exposure compensation for the F5 can be adjusted using Custom Setting 18; 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 photomicrography and macro photography at magnifications of 1: 1 or higher.
Note: The F5 supports matrix metering with A, B, E, EC-B/EC-E, J, and L screens only.
Lens Care
- Do not pick up or hold the lens or camera using only the lens hood.
- Keep the CPU contacts clean.
- S hould the rubber lens-mount gasket be damaged, cease use immedi-ately and take the lens to a Nikon-authorized service center for repair.
- Use a blower to remove dust and lint from the lens surfaces. To remove smudges and fingerprints, apply 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 fingers.
- Never use organic solvents such as paint thinner or benzene to clean the lens.
- The lens hood or NC filters can be used to protect the front lens element.
- Attach the front and rear caps before placing the lens in its flexible pouch.
- If the lens will not be used for an extended period, store it in a cool, dry loca-tion to prevent mold and rust. Do not store in direct sunlight or with naphtha or camphor moth balls.
- Keep the lens dry. Rusting of the internal mechanism can cause irrepa-rable damage.
- Leaving the lens in extremely hot locations could damage or warp parts made from reinforced plastic.
