Key Components:

• Zoom Ring: Used to adjust the focal length between 100mm and 200mm.
• Focus Ring: Used for manual focusing.
• Aperture Ring: Allows for manual control of the lens aperture.
• Focus Limiter Switch: Restricts the autofocus range for faster focusing in specific scenarios (e.g., FULL, 5m-∞).
• OIS (Optical Image Stabilization) Switch: Activates or deactivates the image stabilization function.
• Tripod Collar Foot: Provides a stable mounting point for the lens on a tripod, allowing for better balance.

4. Installation and Setup

Attaching the Lens to the Camera:

1. Ensure both the camera and lens are powered off.
2. Remove the rear lens cap from the lens and the body cap from the camera.
3. Align the mounting index (white dot) on the lens with the mounting index on the camera body.
4. Insert the lens into the camera mount and rotate it clockwise until it clicks into place. Do not force the lens.

Attaching the Lens Hood:

Align the mark on the lens hood with the mark on the front of the lens and rotate the hood until it locks into place. The lens hood helps to prevent stray light from entering the lens and causing flare, and also offers some physical protection to the front element.

Using the Tripod Collar Foot:

The integrated tripod collar foot allows for stable mounting of the lens and camera system on a tripod. This is particularly useful for a lens of this size and weight, as it shifts the balance point to the lens, reducing strain on the camera's lens mount. The foot can be rotated to adjust the camera's orientation without removing it from the tripod.

5. Operation

Autofocus (LM - Linear Motor):

The lens features a Linear Motor (LM) for autofocus, which provides accurate, quiet, and high-speed focusing. To use autofocus, ensure your camera's focus mode is set to AF. The lens also includes a mechanism to secure the linear motor when the camera is powered off or during image playback, preventing unintended movement of lens elements.

Optical Image Stabilization (OIS):

The lens is equipped with a powerful 5-stop Optical Image Stabilization system (CIPA guidelines). This feature helps to reduce blur caused by camera shake, especially when shooting handheld at slower shutter speeds or longer focal lengths. To activate OIS, set the OIS switch on the lens barrel to "ON".

Zooming:

Rotate the zoom ring on the lens barrel to adjust the focal length between 100mm and 200mm. The focal length markings are indicated on the lens barrel.

Using the FUJINON GF1.4x TC WR Teleconverter:

This lens is compatible with the FUJINON GF1.4x TC WR teleconverter (sold separately). Attaching this teleconverter extends the focal length range to 140-280mm (equivalent to 111-221mm in 35mm format) while maintaining image quality. Refer to the teleconverter's manual for specific attachment instructions.

6. Care and Maintenance

Cleaning the Lens:

• Use a blower brush to remove dust and loose particles from the lens surfaces.
• For smudges or fingerprints, use a clean, soft microfiber lens cloth. For stubborn marks, apply a small amount of lens cleaning solution to the cloth (not directly to the lens) and gently wipe in a circular motion from the center outwards.
• Avoid touching the lens elements with your fingers.

Storage:

• When not in use, always attach the front and rear lens caps to protect the elements.
• Store the lens in a cool, dry place, away from direct sunlight and extreme temperatures.
• If storing for extended periods, consider using a dehumidifying cabinet or silica gel packets to prevent mold growth.

Dust and Weather Resistance (WR):

The lens is sealed in 10 areas to provide dust and weather resistance, allowing it to operate in temperatures down to 14 degrees Fahrenheit (-10 degrees Celsius). While designed for robust environments, avoid exposing the lens to excessive moisture or dust when possible. If the lens gets wet, wipe it dry with a clean cloth as soon as possible.

7. Troubleshooting

Common Issues and Solutions:

• Lens not recognized by camera:
  • Ensure the lens is securely attached to the camera body. Remove and re-attach the lens, ensuring it clicks into place.
  • Clean the lens and camera electrical contacts with a clean, dry cloth.
  • Ensure the camera firmware is up to date.
• Autofocus is slow or inaccurate:
  • Check the focus mode on your camera and lens (e.g., ensure it's set to AF).
  • Verify the focus limiter switch on the lens is set appropriately for your shooting distance (e.g., "FULL" for full range, or "5m-∞" for distant subjects).
  • Ensure there is sufficient light and contrast in your subject for the autofocus system to work effectively.
• Images are blurry despite OIS being on:
  • Ensure the OIS switch on the lens is set to "ON".
  • Image stabilization compensates for camera shake, but not subject motion. If your subject is moving, use a faster shutter speed.
  • In very low light or with extremely slow shutter speeds, a tripod is still recommended for optimal sharpness.
• Dust or spots visible in images:
  • Clean the front and rear elements of the lens as described in the "Care and Maintenance" section.
  • If spots persist, they may be on the camera sensor. Refer to your camera's manual for sensor cleaning procedures or consult a professional.
