Vibration Reduction (VR)
The lens supports vibration reduction. Vibration reduction settings can be
adjusted from the camera. See the documentation provided with the camera for
details.
Vibration reduction allows shutter speeds slower than would otherwise be the
case, expanding the range of shutter speeds available.
Vibration Reduction
• Due to the design of the vibration reduction system, the lens may rattle when
shaken. This does not indicate a malfunction.
• To reduce blur caused by tripod shake, select [Normal] or [Sport] for the on-
camera vibration reduction option when the camera is mounted on a tripod.
Note, however, that depending on the type of tripod and shooting
conditions, there may be cases in which [Off] is the preferred option.
• [Normal] or [Sport] is recommended when the camera is mounted on a
monopod.
16 Vibration Reduction (VR)

Cautions: Taking Photographs
• The following restrictions apply when the lens is used with an FX-format
camera:
The camera will use the DX-format image area, which reduces the number of
pixels recorded and the number of focus points.
The [Image Dust Off ref photo] option in the setup menu cannot be used.
• Videos shot with 1920 × 1080 120p, 1920 × 1080 100p, or 1920 × 1080 slow-
motion selected for [Frame size/frame rate] in the movie shooting menu are
recorded at the following frame sizes and rates when the lens is mounted on a
Z 6:
1920 × 1080; 120p → 1920 × 1080; 60p
1920 × 1080; 100p → 1920 × 1080; 50p
1920 × 1080; 30p ×4 (slow-motion) → 1920 × 1080; 30p
1920 × 1080; 25p ×4 (slow-motion) → 1920 × 1080; 25p
1920 × 1080; 24p ×5 (slow-motion) → 1920 × 1080; 24p

Precautions for Use
• Do not pick up or hold the lens or camera using only the lens caps or lens
hood.
• Keep the CPU contacts clean.
• Reattach the lens caps when the lens is not in use.
• Do not leave the lens in humid locations or in locations in which it may be
exposed to moisture. Rusting of the internal mechanism can cause irreparable
damage.
• Do not leave the lens next to open flames or in other extremely hot locations.
Extreme heat could damage or warp the lens.
• Taking the lens from a warm to a cold environment or vice versa may cause
damaging condensation inside and outside the lens. Place the lens in a sealed
bag or plastic case before taking it across a temperature boundary. The lens can
be taken from the bag or case once it has had time to adjust to the new
temperature.
• We recommend that you place the lens in a case (available separately) to
protect it from scratches during transport.
18 Precautions for Use

Lens Maintenance
• Removing dust is normally sufficient to clean the glass surfaces of the lens.
• Smudges, fingerprints, and other oily stains can be removed using a soft, clean
cotton cloth or third-party lens cleaning tissue lightly dampened with a small
amount of ethanol or third-party lens cleaner; clean from the center outwards in
a circular motion. Be sure to clean evenly and thoroughly without leaving
smears.
• Never use organic solvents such as paint thinner or benzene to clean the lens.
• Neutral Color (NC) filters (available separately) and the like can be used to
protect the front lens element.
• Do not store the lens in direct sunlight or with naphtha or camphor moth balls.
If the lens will not be used for an extended period, store it in a cool, dry location
to prevent mold and rust.
