Mounting the Filter

  • If two or more filters are mounted at the same time, vignetting may occur.
  • Check if the filter size is compatible with the lens (refer to “Product specifications”) and then mount it at the front of the lens.

Mounting the Hood

• The hood blocks unnecessary light and protects the front surface of the lens from rain, snow, and dust.
• Align the mount position index indicated on the hood with the hood index (white) indicated on the lens, and rotate the hood clockwise until a clicking sound occurs. The hood is now fixed
• You can store the hood by mounting it on the lens in the opposite direction.
• Caution: Improper mounting of the hood hides the lens angle and causes vignetting

Zooming

• You can take pictures using various focal lengths (wide angle 35mm – telescopic 150mm) by turning the zoom ring.
• How to use the focus hold button
• If the switch is in the AF position: It operates as the general focus hold button; It can be set for different functions depending on the camera body.

If the switch is in the MF position, or the camera body setting is MF: This function allows the user to save the focus at any desired position.

• When you press and hold down the focus hold button for 3 seconds, the screen blinks and informs you of the saving status. When you press the button briefly, the focus moves to a saved position.

  • MODE 1, 2: The Par Focal function that maintains focus when zooming in and out can be used.
  • MODE 3 : The Dolly shot function, in which the size of the subject is fixed and the magnification of the background is changed when zooming in and out, can be used.
  • When the AF/MF switch is in the AF position
  • MODE 2: The focusing ring operates with the aperture adjustment function.

Safety Caution

• Do not look at the sun or other strong light through the lens or camera. Doing so may cause blindness.
• Do not store the lens without a lens cap in a location with direct sunlight, such as inside a vehicle. Direct sunlight passing through the lens may be concentrated, causing a fire.
  • Keep the lens out of the reach of children. Failure to do so may cause an accident or personal injury.

Cautions for Use

• To use the lens safely, attach or detach the lens while the camera is turned off.
• Be careful not to touch or contaminate the contact point on the mount. If electronic signals are not transmitted between the camera and the lens smoothly, a malfunction may occur.
• Do not apply excessive force to the lens when attached to the camera. Doing so may cause damage to the lens and/or camera mounts.
• It is recommended to use a strong tripod. If a weak tripod is used, the tripod may fall, damaging the camera and/or the lens.
• If the lens is placed in a hot location, damage or distortion may occur, resulting in performance problems.
• Take care not to get the lens wet with water or other liquids, and store the lens in a dry place with ventilation.
• If the lens is wet or if you use the lens with wet hands, product failure, fire, or electric shock may occur.
• Avoid direct sunlight, and do not store the lens near naphthalene or mothballs.
• Avoid using the lens in a location with drastic temperature changes. In particular, if you move a lens that has been chilled in a cold location to a warm location, moisture in the air may be concentrated outside or inside the lens, causing a failure or the production of mold. In such a case,  keep the lens in a plastic bag or an exclusive camera bag and take it out when the temperature of the lens becomes similar to the peripheral temperature.
• If the lens surface gets dirty, dust it off using a lens blower or a brush and wipe it with a clean soft cloth (cleaning tissue, cotton cloth, etc.).
• When dusting or cleaning the lens, use ethanol or lens cleaner, and do not use organic solvents such as thinner, alcohol, or benzene.
