3. Align the mounting index mark on the lens (usually a white dot) with the corresponding mark on the camera body.

3.2 Attaching the Lens Hood

The included lens hood helps to block extraneous light, reducing flare and ghosting, and provides physical protection to the front element. Align the lens hood with the front of the lens and rotate it until it locks into place. For storage, the hood can be reversed and mounted onto the lens.

3.3 Using the Tripod Collar

The removable tripod collar allows for better balance when mounting the lens and camera on a tripod or monopod, especially given the lens's weight. Loosen the locking knob on the collar to rotate the lens for horizontal or vertical shooting, or to remove the collar entirely if not needed.

4. Operating Instructions

4.1 Autofocus (AF) and Manual Focus (MF)

• AF/MF Switch: Locate the AF/MF switch on the lens barrel. Slide it to 'AF' for autofocus or 'MF' for manual focus.
• Autofocus Operation: In AF mode, the lens will automatically focus when the camera's shutter button is half-pressed. The built-in motor provides focusing for compatible Nikon bodies.
• Manual Focus Operation: In MF mode, rotate the focus ring on the lens barrel to adjust focus manually. Use the camera's viewfinder or live view to confirm sharpness.

4.2 Zooming

Rotate the zoom ring on the lens barrel to change the focal length between 70mm and 200mm. The focal length markings are indicated on the lens barrel.

4.3 Aperture Control

This lens features a constant maximum aperture of f/2.8 across its entire zoom range. Aperture settings are controlled via your camera body. Refer to your camera's instruction manual for details on setting aperture, shutter speed, and ISO.

4.4 Macro Photography

The lens offers a macro magnification ratio of 1:3.1 at the 200mm focal length, with a minimum focus distance of 0.95m (37.4 inches). This allows for detailed close-up shots of smaller subjects.

5. Maintenance and Care

• Cleaning the Lens: Use a soft, clean microfiber cloth specifically designed for optics to gently wipe dust and smudges from the lens elements. For stubborn marks, use a small amount of lens cleaning fluid applied to the cloth, not directly to the lens.
• Cleaning the Lens Body: Wipe the lens barrel with a soft, dry cloth. Avoid using harsh chemicals or solvents.
• Storage: When not in use, store the lens with both front and rear caps attached in a cool, dry place, away from direct sunlight and extreme temperatures. Consider using a dehumidifying cabinet or silica gel packs in humid environments to prevent mold growth.
• Handling: Avoid dropping or subjecting the lens to strong impacts. Do not touch the lens elements with your fingers.
• Water and Dust: This lens is not weather-sealed. Avoid exposure to rain, snow, or excessive dust.

6. Troubleshooting

• Autofocus is slow or hunts:
  • Ensure sufficient light is available for the autofocus system.
  • Check that the AF/MF switch on the lens is set to 'AF'.
  • Verify that the camera's autofocus mode is correctly set.
  • In very low light, try focusing on a high-contrast area.
• Images are blurry or not sharp:
  • Check if the lens is properly focused (either manually or via autofocus).
  • Ensure the shutter speed is fast enough to prevent camera shake, especially at longer focal lengths (e.g., 1/200s or faster at 200mm).
  • Clean the front and rear lens elements.
  • Use a tripod for maximum sharpness, particularly in low light or with slower shutter speeds.
• Lens not recognized by camera:
  • Ensure the lens is securely attached to the camera body.
  • Clean the electrical contacts on both the lens mount and camera body with a clean, dry cloth.
  • Power cycle the camera (turn off, remove battery, reinsert, turn on).

If problems persist, consult a qualified service technician or contact Tamron customer support.
