Lens Installation and Detachment

  • Attaching the lens
    – Remove the front and rear caps of the lens.
    – Align the mount index indicated on the lens with the lens mount index indicated on the camera mount, then rotate the lens clockwise until a clicking sound occurs.

  • Detaching the lens
    – With the camera lens-detaching button pressed, detach the lens by rotating it counterclockwise until the lens stops.

Mounting the Filter

  • A filter can be mounted on the filter mounting screw at the front of the lens.
    – 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, 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.

Using the Custom Switch

  • Use the custom switch to set the focus ring to control functions such as aperture adjustment.
    – MODE 1: Works as a focus adjustment function (If the camera focusing method is in the MF mode)
    – MODE 2: Operate with the Preset Aperture Control function (when the focusing mode of the camera is set to AF)
    ※ The Preset Aperture Control function is for video shooting only. It is recommended to be used in Preset mode in F No 1.8, the AF operation may not function correctly when converted from F No 2.0 or higher.
    ※ Refer to the homepage for a detailed explanation.

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**

  • In order 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.
